Trait PersistExt 

pub trait PersistExt: Persist {
    // Required method
    async fn mutate<R>(
        &mut self,
        mutation: impl FnOnce(&mut Self::Target) -> R,
    ) -> Result<R, Self::Error>;
}

Extension methods provided for every Persist implementation.

Required Methods

async fn mutate<R>( &mut self, mutation: impl FnOnce(&mut Self::Target) -> R, ) -> Result<R, Self::Error>

Applies a mutation to the value, persisting when done.

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.
