Trait ResultExt 

pub trait ResultExt<T, E>: Sized {
    // Required methods
    fn extend_err<C>(self, cb: C) -> Result<T>
       where C: FnOnce(&E, &mut ErrorExtensionValues);
    fn extend(self) -> Result<T>;
}

Extend a Result’s error value with ErrorExtensions.

Required Methods

fn extend_err<C>(self, cb: C) -> Result<T>

where C: FnOnce(&E, &mut ErrorExtensionValues),

Extend the error value of the result with the callback.

fn extend(self) -> Result<T>

Extend the result to a Result.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
