pub struct DueDeletions { /* private fields */ }Expand description
Retired segment files whose deletion delay has passed, taken out of the
log by Log::maintain_deferring_deletions.
Unlinking a large segment file drops its page cache, which takes tens of milliseconds a file on a loaded disk. Holding the files here lets the caller delete them without holding the log, so the appends and reads of the partition do not wait for it.

Source§impl DueDeletions
impl DueDeletions
Sourcepub fn delete(self) -> Result<(), FailedDeletion>
pub fn delete(self) -> Result<(), FailedDeletion>
Delete the files, newest name first within each retired segment, as
Log::maintain does.
§Errors
Stops at the first file that fails to delete and returns the error with every file not yet deleted.

§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>
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;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§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>
renamed to 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);
