}Expand description
Errors and warnings that can occur during string unescaping. They mostly relate to malformed escape sequences, but there are a few that are about other problems.
Variants§
ZeroChars
Expected 1 char, but 0 were found.
MoreThanOneChar
Expected 1 char, but more than 1 were found.
LoneSlash
Escaped ’' character without continuation.
InvalidEscape
Invalid escape character (e.g. ‘\z’).
BareCarriageReturn
Raw ‘\r’ encountered.
BareCarriageReturnInRawString
Raw ‘\r’ encountered in raw string.
EscapeOnlyChar
Unescaped character that was expected to be escaped (e.g. raw ‘\t’).
TooShortHexEscape
Numeric character escape is too short (e.g. ‘\x1’).
InvalidCharInHexEscape
Invalid character in numeric escape (e.g. ‘\xz’)
OutOfRangeHexEscape
Character code in numeric escape is non-ascii (e.g. ‘\xFF’).
NoBraceInUnicodeEscape

‘\u{_12}’
OverlongUnicodeEscape
More than 6 characters in ‘\u{..}’, e.g. ‘\u{10FFFF_FF}’
LoneSurrogateUnicodeEscape
Invalid in-bound unicode character code, e.g. ‘\u{DFFF}’.
OutOfRangeUnicodeEscape
Out of bounds unicode character code, e.g. ‘\u{FFFFFF}’.
UnicodeEscapeInByte
Unicode escape code in byte literal.
NonAsciiCharInByte
Non-ascii character in byte literal, byte string literal, or raw byte string literal.
NulInCStr
UnskippedWhitespaceWarning
After a line ending with ’', the next line contains whitespace characters that are not skipped.

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>

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;
painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

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>
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.
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);
