Trait StdErrorExt 

pub trait StdErrorExt
where
    Self: StdError,
{
    // Provided methods
    fn as_chain(&self) -> String { ... }
    fn into_boxed(self) -> BoxError
       where Self: Sized + Send + Sync + 'static { ... }
}

Extension methods for std errors.

Provided Methods

fn as_chain(&self) -> String

Format this error as a chain of colon separated strings built from this error and all recursive sources.

Can be used to log errors like this:

error!(error = error.as_chain(), "cannot do this or that");

fn into_boxed(self) -> BoxError

where Self: Sized + Send + Sync + 'static,

Converts this error – given it implements Sized + Send +Sync and 'static – into a BoxError.

Dyn Compatibility

This trait is dyn compatible.

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