pub dropped_count: u64,
pub last_sequence: Option<EventSequence>,
}Expand description
Fixed-capacity lifecycle event journal.
Fields§
§capacity: usizeMaximum number of events retained in memory.
events: VecDeque<SupervisorEvent>Recent events in oldest-to-newest order.
dropped_count: u64Number of events dropped because capacity was full.
last_sequence: Option<EventSequence>Last sequence written to the journal.
Implementations§
Source§impl EventJournal
impl EventJournal
Sourcepub fn new(capacity: usize) -> Self
pub fn new(capacity: usize) -> Self
Creates an event journal with fixed capacity.
§Arguments
capacity: Maximum number of events retained. Zero is allowed and drops every pushed event.
§Returns
Returns an empty EventJournal.
§Examples
let journal = rust_supervisor::journal::ring::EventJournal::new(2);
assert_eq!(journal.capacity, 2);Sourcepub fn push(&mut self, event: SupervisorEvent) -> u64
pub fn push(&mut self, event: SupervisorEvent) -> u64
Sourcepub fn recent(&self, limit: usize) -> Vec<SupervisorEvent>
pub fn recent(&self, limit: usize) -> Vec<SupervisorEvent>

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>

Source§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().

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.

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);
