Enum ColorParseError 

#[non_exhaustive]
pub enum ColorParseError {
    InvalidLength,
    InvalidHexDigit,
    Unknown,
}

Error returned when Color fails to parse from a string.

Produced by the std::str::FromStr implementation for Color.

Example

use slt::Color;

let err = "#zz0011".parse::<Color>().unwrap_err();
// Display renders a human-readable reason.
assert!(err.to_string().contains("non-hex digit"));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidLength

The input had a hex form (#… or all hex-looking) but the wrong number of digits (only 3 or 6 are accepted).

InvalidHexDigit

The input contained a character that is not a valid hex digit.

Unknown

The input did not match any known hex form or named color.

Trait Implementations

impl Clone for ColorParseError

fn clone(&self) -> ColorParseError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColorParseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ColorParseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ColorParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Hash for ColorParseError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColorParseError

fn eq(&self, other: &ColorParseError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
