Struct StateBuilder
pub struct StateBuilder<DB> { /* private fields */ }Expand description
Allows building of State and initializing it with different options.
Implementations§
§impl StateBuilder<EmptyDBTyped<Infallible>>
impl StateBuilder<EmptyDBTyped<Infallible>>
pub fn new() -> StateBuilder<EmptyDBTyped<Infallible>>
pub fn new() -> StateBuilder<EmptyDBTyped<Infallible>>
Create a new builder with an empty database.
If you want to instantiate it with a specific database, use
new_with_database.
§impl<DB> StateBuilder<DB>where
DB: Database,
impl<DB> StateBuilder<DB>where
DB: Database,
pub fn new_with_database(database: DB) -> StateBuilder<DB>
pub fn new_with_database(database: DB) -> StateBuilder<DB>
Create a new builder with the given database.
pub fn with_database<ODB>(self, database: ODB) -> StateBuilder<ODB>where
ODB: Database,
pub fn with_database<ODB>(self, database: ODB) -> StateBuilder<ODB>where
ODB: Database,
Set the database.
pub fn with_database_ref<ODB>(
self,
database: ODB,
) -> StateBuilder<WrapDatabaseRef<ODB>>where
ODB: DatabaseRef,
pub fn with_database_ref<ODB>(
self,
database: ODB,
) -> StateBuilder<WrapDatabaseRef<ODB>>where
ODB: DatabaseRef,
Takes DatabaseRef and wraps it with WrapDatabaseRef.
pub fn with_database_boxed<Error>(
self,
database: Box<dyn Database<Error = Error> + Send + '_>,
) -> StateBuilder<Box<dyn Database<Error = Error> + Send + '_>>
pub fn with_database_boxed<Error>( self, database: Box<dyn Database<Error = Error> + Send + '_>, ) -> StateBuilder<Box<dyn Database<Error = Error> + Send + '_>>
With boxed version of database.
pub fn without_state_clear(self) -> StateBuilder<DB>
pub fn without_state_clear(self) -> StateBuilder<DB>
By default state clear flag is enabled but for initial sync on mainnet we want to disable it so proper consensus changes are in place.
pub fn with_bundle_prestate(self, bundle: BundleState) -> StateBuilder<DB>
pub fn with_bundle_prestate(self, bundle: BundleState) -> StateBuilder<DB>
Allows setting prestate that is going to be used for execution. This bundle state will act as additional layer of cache. and State after not finding data inside StateCache will try to find it inside BundleState.
On update Bundle state will be changed and updated.
pub fn with_bundle_update(self) -> StateBuilder<DB>
pub fn with_bundle_update(self) -> StateBuilder<DB>
Make transitions and update bundle state.
This is needed option if we want to create reverts and getting output of changed states.
pub fn with_cached_prestate(self, cache: CacheState) -> StateBuilder<DB>
pub fn with_cached_prestate(self, cache: CacheState) -> StateBuilder<DB>
It will use different cache for the state. If set, it will ignore bundle prestate.
and will ignore without_state_clear flag as cache contains its own state_clear flag.
This is useful for testing.
pub fn with_background_transition_merge(self) -> StateBuilder<DB>
pub fn with_background_transition_merge(self) -> StateBuilder<DB>
Starts the thread that will take transitions and do merge to the bundle state in the background.
pub fn with_block_hashes( self, block_hashes: BTreeMap<u64, FixedBytes<32>>, ) -> StateBuilder<DB>
pub fn build(self) -> State<DB>

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);§impl<T> Pipe for Twhere
