Trait ResultExt

pub trait ResultExt<T, E> {
    // Required methods
    fn unwrap_chain(self) -> T;
    fn expect_chain(self, msg: &str) -> T;
}

A helper extension trait to “unwrap” results with an error chain.

Required Methods

fn unwrap_chain(self) -> T

Like Result::unwrap, but wraps the error in the DisplayErrorChain and prints out the full chain in case an Err(_) value is encountered.

fn expect_chain(self, msg: &str) -> T

Like Result::expect, but wraps the error in the DisplayErrorChain and prints out the full chain in case an Err(_) value is encountered.
