    // Provided methods
    fn unwrap_mut(
        &mut self,
    ) -> WriteLock<'_, T, Self::Storage, Self::WriteMetadata>

Available on crate feature prelude only.

An extension trait for Writable<Result<T, E>> that provides some convenience methods.

Provided Methods

fn unwrap_mut(&mut self) -> WriteLock<'_, T, Self::Storage, Self::WriteMetadata>

where T: 'static, E: 'static,

Unwraps the inner value mutably, panicking if the Result is an error.

fn as_mut( &mut self, ) -> Result<WriteLock<'_, T, Self::Storage, Self::WriteMetadata>, WriteLock<'_, E, Self::Storage, Self::WriteMetadata>>

where T: 'static, E: 'static,

Attempts to mutably access the inner value of the Result.

Dyn Compatibility

This trait is dyn compatible.

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