Trait linera_client::persistent::LocalPersist

pub trait LocalPersist: Deref {
    type Error: Error + Send + Sync + 'static;

    // Required methods
    fn as_mut(&mut self) -> &mut Self::Target;
    async fn persist(&mut self) -> Result<(), Self::Error>;
    fn into_value(self) -> Self::Target
       where Self::Target: Sized;
}

The Persist trait provides a wrapper around a value that can be saved in a persistent way. A minimal implementation provides an Error type, a persist function to persist the value, and an as_mut function to get a mutable reference to the value in memory.

LocalPersist is a non-Send version.

Required Associated Types

type Error: Error + Send + Sync + 'static

Required Methods

fn as_mut(&mut self) -> &mut Self::Target

Gets a mutable reference to the value. This is not expressed as a DerefMut bound because it is discouraged to use this function! Instead, use mutate.

async fn persist(&mut self) -> Result<(), Self::Error>

Saves the value to persistent storage.

fn into_value(self) -> Self::Target

where Self::Target: Sized,

Takes the value out.

Object Safety

This trait is not object safe.
