Expand description
Convenience trait for converting Result<T, E>
into anyhow::Result<T>
Typically this is automatically done with the ?
operator in Rust and
by default this trait isn’t necessary. With the anyhow
crate’s std
feature disabled, however, the ?
operator won’t work because the Error
trait is not defined. This trait helps to bridge this gap.
This does the same thing as ?
when the std
feature is enabled, and when
std
is disabled it’ll use different trait bounds to create an
anyhow::Error
.
This trait is not suitable as a public interface because features change what implements the trait. It’s good enough for a wasmtime internal implementation detail, however.
