Trait tract_tensorflow::prelude::TractResultExt

pub trait TractResultExt<T> {
    fn chain_err<F, EK>(self, callback: F) -> Result<T, TractError>
    where
        EK: Into<TractErrorKind>,
        F: FnOnce() -> EK;
}

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

Required methods

fn chain_err<F, EK>(self, callback: F) -> Result<T, TractError> where
    EK: Into<TractErrorKind>,
    F: FnOnce() -> EK, 

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.
