pub struct UnifiedPressure { /* private fields */ }Available on crate feature
governor only.Expand description
Combines pressure sources into one level under a hysteretic latch.
See the module docs for the design invariants. The
latch state is an AtomicBool so should_hold
is a cheap, Sync hot-path check.
Implementations§
Source§impl UnifiedPressure
impl UnifiedPressure
Sourcepub fn new(sources: Vec<Arc<dyn PressureSource>>, hyst: Hysteresis) -> Self
pub fn new(sources: Vec<Arc<dyn PressureSource>>, hyst: Hysteresis) -> Self
Build a governor over the given sources and hysteresis band.
Sourcepub fn add_source(&mut self, source: Arc<dyn PressureSource>)
pub fn add_source(&mut self, source: Arc<dyn PressureSource>)
Add a source after construction.
Proves the seam accepts a new signal kind (e.g. a future CPU
source) with zero change to the gate API – existing callers of
level / should_hold are
untouched.
Sourcepub fn level(&self) -> f64
pub fn level(&self) -> f64
Combined pressure level in [0.0, 1.0].
hard_max = max raw reading over HARD sources (never weighted,
never masked). soft_max = max of sample * weight over SOFT
sources. level = hard_max.max(soft_max).
Sourcepub fn should_hold(&self) -> bool
pub fn should_hold(&self) -> bool
Hysteretic hold latch over level.
- Held and
level <= resume_below-> release, returnfalse. - Not held and
level >= pause_above-> arm, returntrue. - Otherwise -> return the current latch state (the band holds it).
Sourcepub fn snapshot(&self) -> UnifiedPressureSnapshot
pub fn snapshot(&self) -> UnifiedPressureSnapshot
Per-source breakdown plus the combined level and latch state.

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};

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.

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.

wrap(), which have the same functionality but are

§Example
Enable wrapping using .quirk():

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

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);
