pub enum Error {
TooLong,
Empty,
InvalidStart(char),
InvalidCharacters(String),
InvalidUnicode,
}Expand description
Errors that can occur during atom tag validation.
These errors represent various validation failures when creating or parsing atom identifiers, ensuring they conform to the required format and constraints for cryptographically secure identification.
Variants§
TooLong
The atom identifier exceeds the maximum allowed length of 128 bytes.
Atom tags are limited in size to ensure efficient storage and processing while maintaining a sufficient character space for meaningful identifiers.
Empty
The atom identifier is empty.
Empty identifiers are not allowed as they provide no meaningful identification for the atom.
InvalidStart(char)
The atom identifier starts with an invalid character.
Atom identifiers must start with a Unicode letter (not numbers, hyphens, underscores, or other non-letter characters) to ensure they are descriptive and follow identifier conventions.
InvalidCharacters(String)
The atom identifier contains invalid characters.
Only Unicode letters, numbers, hyphens, and underscores are permitted in atom identifiers. This ensures compatibility across different systems and maintains readability.
InvalidUnicode
The atom identifier contains invalid Unicode.
Atom identifiers must be valid UTF-8 encoded Unicode strings. This error occurs when the string contains invalid byte sequences or encoding issues.

§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);§impl<T> PolicyExt for Twhere
