Enum LevelError 

#[non_exhaustive]
pub enum LevelError {
    Empty,
    InvalidCharacter(char),
    Parameter,
}

Error that can happen when parsing a level.

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.

Empty

The level must contain at least one character, it cannot be //.

InvalidCharacter(char)

Invalid character in the level.

Parameter

Mixed characters and parameter in level.

A parameter should incapsulate the whole level (e.g. /foo%{bar} is invalid).

Trait Implementations

impl Clone for LevelError

fn clone(&self) -> LevelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LevelError

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

Formats the value using the given formatter.

impl Display for LevelError

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

Formats the value using the given formatter.

impl Error for LevelError

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>)
