Trait ErrorContext 

pub trait ErrorContext<E: Error>
where
    Self: Sized + Into<E>,
{
    // Provided methods
    fn context<T>(fun: impl FnOnce() -> Result<T, Self>) -> Result<T, E> { ... }
    fn context_async<T, F>(
        fun: impl FnOnce() -> F,
    ) -> impl Future<Output = Result<T, E>>
       where F: Future<Output = Result<T, Self>> { ... }
}

Provided Methods

fn context<T>(fun: impl FnOnce() -> Result<T, Self>) -> Result<T, E>

fn context_async<T, F>( fun: impl FnOnce() -> F, ) -> impl Future<Output = Result<T, E>>

where F: Future<Output = Result<T, Self>>,

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.
