Index Trait

Keeps track of where chunks are in the backend

Required methods

#[must_use]fn lookup_chunk<'life0, 'async_trait>(
    &'life0 mut self,
    id: ChunkID
) -> Pin<Box<dyn Future<Output = Option<SegmentDescriptor>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Provides the location of a chunk in the repository

#[must_use]fn set_chunk<'life0, 'async_trait>(
    &'life0 mut self,
    id: ChunkID,
    location: SegmentDescriptor
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Sets the location of a chunk in the repository

#[must_use]fn known_chunks<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = HashSet<ChunkID>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Returns the set of all ChunkIDs known to exist in the Asuran repository.

#[must_use]fn commit_index<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Commits the index

#[must_use]fn count_chunk<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = usize> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Returns the total number of chunks in the index
