pub(super) struct Key {
pub(super) op: Op,
pub(super) room_id: Option<OwnedRoomId>,
pub(super) event_id: Option<OwnedEventId>,
pub(super) window_hash: Option<u64>,
pub(super) ts: Option<MilliSecondsSinceUnixEpoch>,
pub(super) dir: Option<Direction>,
}Expand description
Single-flight dedup key. MissingEvents keys on a content hash of its
request window instead of a single event_id, so two callers asking for the
same window coalesce regardless of event order; see window_hash.
Fields§
§op: OpEndpoint class; two ops over the same event do not coalesce.
room_id: Option<OwnedRoomId>Room the event belongs to, or None for an unscoped fetch.
event_id: Option<OwnedEventId>Sought event, or None for ops that do not key on one.
window_hash: Option<u64>Content hash of the Op::MissingEvents window; None for every other
op, so their coalescing is byte-identical to before.
ts: Option<MilliSecondsSinceUnixEpoch>Op::TimestampToEvent search timestamp; None for every other op, so
distinct-timestamp queries for one room do not coalesce.
dir: Option<Direction>Op::TimestampToEvent search direction; None for every other op, so
opposite-direction queries for one room do not coalesce.

§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;

§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 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 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);§impl<T> Pointable for T
