Expand description
A pending read transaction waiting to be linearized along with metadata about it’s state
Fields§
§txn: PendingRead
The transaction type
timestamp_context: TimestampContext<Timestamp>
The timestamp context of the transaction.
created: Instant
When we created this pending txn, when the transaction ends. Only used for metrics.
num_requeues: u64
Number of times we requeued the processing of this pending read txn.
Requeueing is necessary if the time we executed the query is after the current oracle time;
see Coordinator::message_linearize_reads
for more details.
otel_ctx: OpenTelemetryContext
Telemetry context.

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();

Returns a styled value derived from self

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();

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.
fn clear(&self) -> Painted<&T>
resetting()
due to conflicts with Vec::clear()
.
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);
