Struct Error
pub struct Error { /* private fields */ }Expand description
An error that can occur in this crate.
The most common type of error is a result of overflow. But other errors exist as well:
- Time zone database lookup failure.
- Configuration problem. (For example, trying to round a span with calendar units without providing a relative datetime.)
- An I/O error as a result of trying to open a time zone database from a
directory via
TimeZoneDatabase::from_dir. - Parse errors.
§Introspection is limited
Other than implementing the std::error::Error trait when the
std feature is enabled, the core::fmt::Debug trait and the
core::fmt::Display trait, this error type currently provides no
introspection capabilities.
§Design
This crate follows the “One True God Error Type Pattern,” where only one error type exists for a variety of different operations. This design was chosen after attempting to provide finer grained error types. But finer grained error types proved difficult in the face of composition.
More about this design choice can be found in a GitHub issue about error types.
Implementations§
§impl Error
impl Error
pub fn from_args<'a>(message: Arguments<'a>) -> Error
pub fn from_args<'a>(message: Arguments<'a>) -> Error
Creates a new error value from core::fmt::Arguments.
It is expected to use format_args! from
Rust’s standard library (available in core) to create a
core::fmt::Arguments.
Callers should generally use their own error types. But in some circumstances, it can be convenient to manufacture a Jiff error value specifically.
§Example
use jiff::Error;
let err = Error::from_args(format_args!("something failed"));
assert_eq!(err.to_string(), "something failed");Trait Implementations§

§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 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 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.§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);
