Manifest service

Required Associated Types§

source

type Error: ErrorExt + Send + Sync

source

type MetaAction: MetaAction

source

type MetaActionIterator: MetaActionIterator<Error = Self::Error, MetaAction = Self::MetaAction>

source

type Checkpoint: Checkpoint

Required Methods§

source

fn update<'life0, 'async_trait>( &'life0 self, action: Self::MetaAction, ) -> Pin<Box<dyn Future<Output = Result<ManifestVersion, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Update metadata by the action

source

fn scan<'life0, 'async_trait>( &'life0 self, start: ManifestVersion, end: ManifestVersion, ) -> Pin<Box<dyn Future<Output = Result<Self::MetaActionIterator, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Scan actions which version in range [start, end)

source

fn do_checkpoint<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<Self::Checkpoint>, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Do a checkpoint, it will create a checkpoint and compact actions.

source

fn last_checkpoint<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<Self::Checkpoint>, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the last success checkpoint

source

fn last_version(&self) -> ManifestVersion

Returns the last(or latest) manifest version.

Provided Methods§

source

fn start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Start the service

source

fn stop<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Stop the service

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.
