}Available on crate feature
concurrency only.Expand description
Configuration for a BackgroundSink.
Fields§
§queue_capacity: usizeMaximum queued messages before overflow policy kicks in. Default 10_000.
batch_size: usizeCoalesce up to this many messages into one drain call. Default 256.
flush_interval: DurationFlush a partial batch after this duration even if it’s not full. Default 100 ms.
overflow: OverflowWhat try_push does when the queue is full.
Default Overflow::Drop.
metric_prefix: Option<&'static str>Optional Prometheus metric prefix. When Some("dfe_dlq_file"),
the sink auto-registers and emits:
<prefix>_pushed_total(counter)<prefix>_dropped_total(counter, onlyOverflow::Drop)<prefix>_writes_total(counter, per batch)<prefix>_write_errors_total(counter, per failed batch)<prefix>_pending(gauge, current queue depth)
When None, the sink tracks dropped() / pending() via
internal atomics only – callers can read them but nothing is
published.

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().

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():

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().

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().

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);
