Trait casper_contract::unwrap_or_revert::UnwrapOrRevert

pub trait UnwrapOrRevert<T> {
    // Required methods
    fn unwrap_or_revert(self) -> T;
    fn unwrap_or_revert_with<E: Into<ApiError>>(self, error: E) -> T;
}

A trait which provides syntactic sugar for unwrapping a type or calling runtime::revert if this fails. It is implemented for Result and Option.

Required Methods

fn unwrap_or_revert(self) -> T

Unwraps the value into its inner type or calls runtime::revert with a predetermined error code on failure.

fn unwrap_or_revert_with<E: Into<ApiError>>(self, error: E) -> T

Unwraps the value into its inner type or calls runtime::revert with the provided error on failure.

Object Safety

This trait is not object safe.
