pub struct IntRange {

pub span: Span,
}Expand description
An inclusive integer range, lo..hi, lo.. or ..hi (patterns track,
slice 5, #2699; events slice 4b, #990): the one production a match pattern
and a via schema(...) clause share. At least one bound is present — a bare
.. is the rest marker, never a range. Each bound is an optionally negative
Int literal, parsed permissively: whether it is in range and whether
lo <= hi are checker questions.
Fields§
§lo: Option<i64>§hi: Option<i64>§lo_text: Option<String>The low bound as written (-1_000), digit separators kept; None when
lo is. Only the formatter reads it; a range built without source
(a suggested fix) leaves it None and prints from the value.
hi_text: Option<String>The high bound as written; see lo_text.

Sourcepub fn describe_source(&self) -> String
pub fn describe_source(&self) -> String
As IntRange::describe, but each bound keeps its source spelling
(1_000..2_000), so formatting does not drop digit separators.

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.

renamed to 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);
