Methods

impl Error

fn new<T>(error: T, message: &str) -> Error where T: ErrorDomain

Creates an error with supplied error enum variant and message.

fn is<T>(&self) -> bool where T: ErrorDomain

Checks if the error domain matches T.

fn kind<T>(&self) -> Option<T> where T: ErrorDomain

Tries to convert to a specific error enum.

Returns Some if the error belongs to the enum's error domain and None otherwise.

Examples

if let Some(file_error) = error.kind::<FileError>() {
    match file_error {
        FileError::Exist => ...
        FileError::Isdir => ...
        ...
    }
}

match error {
    Some(FileError::Exist) => ...
    Some(FileError::Isdir) => ...
    ...
}
