Implementations§

Source§

impl<G, M, const BODY_SIZE: usize> GenericJoiner<G, M, BODY_SIZE>
where G: ChunkGet<BODY_SIZE>, M: JoinMode + Send + Sync,

Source

pub async fn new(getter: G, input: M::RootRef) -> Result<Self>

Create an async joiner from a root reference.

Source

pub fn with_concurrency(self, concurrency: usize) -> Self

Set concurrency level for prefetching.

Source

pub const fn size(&self) -> u64

Total file size.

Source

pub const fn position(&self) -> u64

Current read position.

Source

pub const fn root(&self) -> &ChunkAddress

Root address.

Source

pub async fn read_range(&self, offset: u64, len: usize) -> Result<Vec<u8>>

Read a range of bytes with concurrent fetching using the cached frontier.

Source

pub async fn read_all(&self) -> Result<Vec<u8>>

Read entire file into memory.

Source

pub fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Source

pub fn into_stream(self) -> impl Stream<Item = Result<Bytes>>

Convert into a stream of leaf chunk bodies.

Source

pub fn into_reader(self) -> JoinerReader<G, M, BODY_SIZE>

Convert into an AsyncRead reader.
