pub struct ExecutionPayloadValidator<ChainSpec> { /* private fields */ }Expand description
Execution payload validator.
Implementations§
§impl<ChainSpec> ExecutionPayloadValidator<ChainSpec>
impl<ChainSpec> ExecutionPayloadValidator<ChainSpec>
pub const fn new(
chain_spec: Arc<ChainSpec>,
) -> ExecutionPayloadValidator<ChainSpec>
pub const fn new( chain_spec: Arc<ChainSpec>, ) -> ExecutionPayloadValidator<ChainSpec>
Create a new validator.
pub const fn chain_spec(&self) -> &Arc<ChainSpec>
pub const fn chain_spec(&self) -> &Arc<ChainSpec>
Returns the chain spec used by the validator.

pub fn ensure_well_formed_payload<T>(
&self,
payload: ExecutionPayload,
sidecar: ExecutionPayloadSidecar,
) -> Result<SealedBlock<Header, BlockBody<T>>, PayloadError>where
T: SignedTransaction,
pub fn ensure_well_formed_payload<T>(
&self,
payload: ExecutionPayload,
sidecar: ExecutionPayloadSidecar,
) -> Result<SealedBlock<Header, BlockBody<T>>, PayloadError>where
T: SignedTransaction,
Ensures that the given payload does not violate any consensus rules that concern the block’s layout, like:
- missing or invalid base fee
- invalid extra data
- invalid transactions
- incorrect hash
- the versioned hashes passed with the payload do not exactly match transaction versioned hashes
- the block does not contain blob transactions if it is pre-cancun
The checks are done in the order that conforms with the engine-API specification.
This is intended to be invoked after receiving the payload from the CLI.
The additional MaybeCancunPayloadFields are not part of the payload, but are additional fields in the engine_newPayloadV3 RPC call, See also https://github.com/ethereum/execution-apis/blob/fe8e13c288c592ec154ce25c534e26cb7ce0530d/src/engine/cancun.md#engine_newpayloadv3
If the cancun fields are provided this also validates that the versioned hashes in the block
match the versioned hashes passed in the
CancunPayloadFields, if the cancun payload
fields are provided. If the payload fields are not provided, but versioned hashes exist
in the block, this is considered an error: PayloadError::InvalidVersionedHashes.
This validates versioned hashes according to the Engine API Cancun spec: https://github.com/ethereum/execution-apis/blob/fe8e13c288c592ec154ce25c534e26cb7ce0530d/src/engine/cancun.md#specification

§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
