Trait wafer::errors::ResultExt[−]

pub trait ResultExt<T> {
    fn chain_err<F, EK>(self, callback: F) -> Result<T, Error>
    where
        F: FnOnce() -> EK,
        EK: Into<ErrorKind>;
}

Additional methods for Result, for easy interaction with this crate.

Required Methods

If the Result is an Err then chain_err evaluates the closure, which returns some type that can be converted to ErrorKind, boxes the original error to store as the cause, then returns a new error containing the original error.
