pub struct Interval { /* private fields */ }Expand description
A recurring interval timer.
Obtain one via interval. Call .tick().await to wait for each period.
On native the first tick() returns immediately (matches Tokio semantics).
On WASM the first tick() waits one full period. The primary consumer
(sync keepalive) tolerates either behaviour.
Implementations§
Source§impl Interval
impl Interval
Sourcepub fn delay_missed_ticks(&mut self)
pub fn delay_missed_ticks(&mut self)
Measure the next period from when this tick is consumed rather than from the schedule, so a slow consumer does not come back to a burst of catch-up ticks.
Tokio’s default replays every missed tick immediately. For a periodic task whose work can outlast its own period — a flush, say — that turns one slow pass into back-to-back passes with no gap between them, and the task never yields long enough for anything else to make progress. On WASM each tick already sleeps a full period after the previous one, so this is the behaviour there either way.

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>

Returns a styled value derived from self with the background set to

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():

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().

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};

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);Source§impl<T> Pointable for T
