pub struct CssError { /* private fields */ }Expand description
Represents a located error that happened while parsing CSS.
This class is meant to be an improvement over ParseError in order to provide better
error reporting.
ParseError by only contains SourceLocation which includes line and column numbers.
This is not enough to provide a good error report.
CssError contains:
- Optional code of the error type.
- Generic message of the error type.
- Annotated message specific to the error.
- Specific location of the error, specified with a byte range.
- It’s possible to provide a less specific location, and later will automatically upgrade when more information is available.
It contains handy From conversions, so it can be used with existing Parser methods like Parser::expect_integer()?
Implementations§
Source§impl CssError
impl CssError
Sourcepub fn new_located<T>(
located: &Located<T>,
code: CssErrorCode,
annotated_message: impl Into<String>,
) -> Self
pub fn new_located<T>( located: &Located<T>, code: CssErrorCode, annotated_message: impl Into<String>, ) -> Self
New error with specific location. This constructor is the preferred way to create a new error.
Located items can be obtained using methods from ParserExt trait.
Sourcepub fn new_unlocated(
code: CssErrorCode,
annotated_message: impl Into<String>,
) -> Self
pub fn new_unlocated( code: CssErrorCode, annotated_message: impl Into<String>, ) -> Self
New error where the location is unknown.
Is ok to construct errors this way when implementing crate::reflect::ReflectParseCss,
since the location will be automatically upgraded to the current line.
Sourcepub fn into_parse_error(self) -> ParseError<'static, CssError>
pub fn into_parse_error(self) -> ParseError<'static, CssError>
Converts this error into a ParseError setting itself as a custom type.
It can covert back to a CssError using CssError::from(parse_error).
Sourcepub fn into_context_less_report(self) -> String
pub fn into_context_less_report(self) -> String
Converts this error into a message without any context.

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().

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.
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);
