Trait ocl_core::error::ChainErr

pub trait ChainErr<T, E> {
    fn chain_err<F, IE>(self, callback: F) -> Result<T, Error>
    where
        F: FnOnce() -> IE,
        IE: Into<Error>;
}

An chainable error.

Required Methods

fn chain_err<F, IE>(self, callback: F) -> Result<T, Error> where
    F: FnOnce() -> IE,
    IE: Into<Error>, 

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.
