Implementations§
Source§impl ExplaineeStatement
impl ExplaineeStatement
pub fn depends_on(&self) -> BTreeSet<GlobalId>
Sourcepub fn broken(&self) -> bool
pub fn broken(&self) -> bool
Statements that have their broken
flag set are expected to cause a
panic in the optimizer code. In this case:
- The optimizer pipeline execution will stop, but the panic will be intercepted and will not propagate to the caller. The partial optimizer trace collected until this point will be available.
- The optimizer trace tracing subscriber will delegate regular tracing spans and events to the default subscriber.
This is useful when debugging queries that cause panics.

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()

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;

Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting()

.
The clear()

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);
