Trait ResultExt 

pub trait ResultExt {
    type Ok;
    type Err;

    // Required method
    fn or_raise<E>(self, err: impl FnOnce() -> E) -> Result<Self::Ok, Err<E>>
       where E: ErrorTrait + Send + Sync + 'static;
}

Required Associated Types

type Ok

type Err

Required Methods

fn or_raise<E>(self, err: impl FnOnce() -> E) -> Result<Self::Ok, Err<E>>

Dyn Compatibility

This trait is not dyn compatible.

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