pub struct LockRank(/* private fields */);Expand description
Ordinal encoding the global lock-acquisition order.
Locks MUST be acquired in strictly ascending rank; the debug-only
assert_lock_order enforces this in debug builds. The type is a thin
newtype over u8 and derives a total ordering.
Implementations§
Source§impl LockRank
impl LockRank
Sourcepub const GPU_VECTORS_SNAPSHOT: LockRank
pub const GPU_VECTORS_SNAPSHOT: LockRank
GPU vector snapshot lock — lowest core rank.
Sourcepub const PREMIUM_MIN: u8 = 40
pub const PREMIUM_MIN: u8 = 40
Inclusive lower bound of the reserved premium rank range.
Core never assigns ranks at or above this value; premium declares
cluster-state / tenant-store / server-level ranks within [40, 59]
without colliding with core.
Sourcepub const PREMIUM_MAX: u8 = 59
pub const PREMIUM_MAX: u8 = 59
Inclusive upper bound of the reserved premium rank range.
Constructs a premium-owned rank, clamped to the reserved range.
Returns None if value is outside the inclusive range
[PREMIUM_MIN, PREMIUM_MAX] (i.e. [40, 59]).

Source§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();Source§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().

Source§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();Source§fn rapid_blink(&self) -> Painted<&T>

Source§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();Source§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.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§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);
