}Expand description
Errors that qsu will return to application.
Variants§
App(AppErr)
Application-defined error.
Applications can use this variant to pass application-specific errors through the runtime back to itself.
ArgP(ArgsError)
BadFormat(String)
Internal(String)
IO(String)
LumberJack(String)
An error related to logging occurred.
This includes both initialization and actual logging.
On Windows errors such as failure to register an event source will be treated as this error variant as well.
Missing(String)
Missing expected data.
Rocket(String)
rocket only.Rocket-specific errors.
SubSystem(String)
SrvApp(AppErrors)
rt only.Returned by RunCtx::run() to indicate which
server application callbacks that failed.
Unsupported
Implementations§
source§impl Error
impl Error
pub fn is_apperr(&self) -> bool
sourcepub fn try_into_apperr<E>(self) -> Result<E, Error>
pub fn try_into_apperr<E>(self) -> Result<E, Error>
Attempt to convert Error into application-specific error.
If it’s not an Error::App() nor can be downcast to type E, the error
will be returned back as an Err().

§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();§fn bright_black(&self) -> Painted<&T>

§fn bright_white(&self) -> Painted<&T>
fn bright_white(&self) -> Painted<&T>
§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().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§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 rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§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();§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);
