Errors produced during tokenization of a farben markup string.

Variants

UnclosedTag(usize)

A [ was found with no matching ].

InvalidTag

The tag name is not a recognized keyword or color form.

Fields

tag_content: String

The raw text inside the brackets, e.g. "floob" for [floob].

position: usize

Byte offset of the opening [ in the original input.

UnclosedValue(usize)

A color value function (e.g. rgb( or ansi() was opened but never closed.

InvalidArgumentCount

A color function received the wrong number of arguments.

Fields

expected: usize

How many arguments the function requires (e.g. 3 for rgb).

got: usize

How many arguments were actually provided.

position: usize

Byte offset of the function call in the original input.

InvalidValue

An argument could not be parsed into the expected numeric type.

Fields

value: String

The offending argument as written.

position: usize

Byte offset of the function call in the original input.

InvalidResetTarget(usize)

A reset tag was given a target that cannot be reset (e.g. [/reset] or [/prefix]).

Trait Implementations

impl Debug for LexError

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

Formats the value using the given formatter.

impl Display for LexError

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

Formats the value using the given formatter.

impl Error for LexError

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.
