Struct BlockIndices
pub struct BlockIndices { /* private fields */ }Expand description
Internal indices of the blocks and chains.
This is main connection between blocks, chains and canonical chain.
It contains a list of canonical block hashes, forks to child blocks, and a mapping of block hash to chain ID.
Implementations§
§impl BlockIndices
impl BlockIndices
pub fn new(
last_finalized_block: u64,
canonical_chain: BTreeMap<u64, FixedBytes<32>>,
) -> BlockIndices
pub fn new( last_finalized_block: u64, canonical_chain: BTreeMap<u64, FixedBytes<32>>, ) -> BlockIndices
Create new block indices structure
pub const fn fork_to_child(
&self,
) -> &HashMap<FixedBytes<32>, LinkedHashSet<FixedBytes<32>>>
pub const fn fork_to_child( &self, ) -> &HashMap<FixedBytes<32>, LinkedHashSet<FixedBytes<32>>>
Return fork to child indices
pub fn pending_blocks(&self) -> (u64, Vec<FixedBytes<32>>)
pub fn pending_blocks(&self) -> (u64, Vec<FixedBytes<32>>)
Returns all pending block hashes.
Pending blocks are considered blocks that are extending the canonical tip by one block number and have their parent hash set to the canonical tip.
pub const fn last_finalized_block(&self) -> u64
pub const fn last_finalized_block(&self) -> u64
Last finalized block
pub fn canonicalize_blocks(
&mut self,
blocks: &BTreeMap<u64, SealedBlockWithSenders>,
)
pub fn canonicalize_blocks( &mut self, blocks: &BTreeMap<u64, SealedBlockWithSenders>, )
Remove all blocks from canonical list and insert new blocks to it.
It is assumed that blocks are interconnected and that they connect to canonical chain
pub fn canonical_hash(&self, block_number: &u64) -> Option<FixedBytes<32>>
pub fn canonical_hash(&self, block_number: &u64) -> Option<FixedBytes<32>>
Returns the block hash of the canonical block with the given number.
pub fn canonical_number(&self, block_hash: &FixedBytes<32>) -> Option<u64>
pub fn canonical_number(&self, block_hash: &FixedBytes<32>) -> Option<u64>
Returns the block number of the canonical block with the given hash.
pub fn canonical_tip(&self) -> NumHash
pub fn canonical_tip(&self) -> NumHash
get canonical tip

§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
