pub enum UserError<FE, U> {
    Format(FE),
    Io(Error),
    User(U),
}
Expand description

An error that can occur within singlefile, or an error from a user operation.

Variants§

§

Format(FE)

An error caused by an implementation of FileFormat.

§

Io(Error)

An error caused by the filesystem.

§

User(U)

An error caused by the user.

Implementations§

source§

impl<FE, U> UserError<FE, U>

source

pub fn map_into<E, F>(self, f: F) -> E
where Error<FE>: Into<E>, F: FnOnce(U) -> E,

Maps this error into another error. The new error type E must implement From<Error<FE>>. Additionally takes a closure allowing the user to manually convert the user error.
