Enum Parity
pub enum Parity {
Eip155(u64),
NonEip155(bool),
Parity(bool),
}Expand description
The parity of the signature, stored as either a V value (which may include a chain id), or the y-parity.
Variants§
Eip155(u64)
Explicit V value. May be EIP-155 modified.
NonEip155(bool)
Non-EIP155. 27 or 28.
Parity(bool)
Parity flag. True for odd.
Implementations§
§impl Parity
impl Parity
pub const fn chain_id(&self) -> Option<u64>
pub const fn chain_id(&self) -> Option<u64>
Returns the chain ID associated with the V value, if this signature is replay-protected by EIP-155.
pub const fn has_eip155_value(&self) -> bool
pub const fn has_eip155_value(&self) -> bool
Returns true if the signature is replay-protected by EIP-155.
This is true if the V value is 35 or greater. Values less than 35 are either not replay protected (27/28), or are invalid.
pub const fn y_parity_byte(&self) -> u8
pub const fn y_parity_byte(&self) -> u8
Return the y-parity as 0 or 1
pub const fn y_parity_byte_non_eip155(&self) -> Option<u8>
pub const fn y_parity_byte_non_eip155(&self) -> Option<u8>
Return the y-parity byte as 27 or 28, in the case of a non-EIP155 signature.
pub const fn strip_chain_id(&self) -> Parity
pub const fn strip_chain_id(&self) -> Parity
Converts an EIP-155 V value to a non-EIP-155 V value.
This is a nop for non-EIP-155 values.
pub const fn with_chain_id(self, chain_id: u64) -> Parity
pub const fn with_chain_id(self, chain_id: u64) -> Parity
Applies EIP-155 with the given chain ID.
pub const fn recid(&self) -> RecoveryId
k256 only.
pub const fn recid(&self) -> RecoveryId
k256 only.Determines the recovery ID.
pub const fn to_parity_bool(self) -> Parity
pub const fn to_parity_bool(self) -> Parity
Convert to a parity bool, dropping any V information.

§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>

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;

§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
