Trait ResultExt

pub trait ResultExt<T>
where
    Self: Sized,
{
    // Required method
    fn chain_err<C, D>(self, chain: C) -> Result<T>
       where C: FnOnce() -> D,
             D: Into<Error>;
}

Extra convenience functions for results based on core errors.

Required Methods

fn chain_err<C, D>(self, chain: C) -> Result<T>

where C: FnOnce() -> D, D: Into<Error>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
