Struct GenericSyncJoiner 

pub struct GenericSyncJoiner<G, M: JoinMode, const BODY_SIZE: usize = DEFAULT_BODY_SIZE>
where
    G: SyncChunkGet<BODY_SIZE> + Clone + Send + Sync,
{ /* private fields */ }

Generic joiner parameterized by chunk mode.

Uses BFS fan-out to pre-expand intermediate nodes into a frontier of roughly equal-sized subtrees. Implements std::io::Read and std::io::Seek for bounded-memory streaming.

Implementations

impl<G, M, const BODY_SIZE: usize> GenericSyncJoiner<G, M, BODY_SIZE>

where G: SyncChunkGet<BODY_SIZE> + Clone + Send + Sync, M: JoinMode + Send + Sync,

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

Create a joiner from a root reference.

pub const fn size(&self) -> u64

Total file size.

pub const fn position(&self) -> u64

Current read position.

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

Root address.

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

Read a range of bytes, fetching required chunks in parallel.

where G: SyncChunkGet<BODY_SIZE> + Clone + Send + Sync, M: JoinMode + Send + Sync,

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

fn read_array<const N: usize>(&mut self) -> Result<[u8; N], Error>

where Self: Sized,

🔬This is a nightly-only experimental API. (read_array)

where G: SyncChunkGet<BODY_SIZE> + Clone + Send + Sync, M: JoinMode + Send + Sync,

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

Seek to an offset, in bytes, in a stream.

fn rewind(&mut self) -> Result<(), Error>

Rewind to the beginning of a stream.

fn stream_len(&mut self) -> Result<u64, Error>

🔬This is a nightly-only experimental API. (seek_stream_len)

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

Returns the current seek position from the start of the stream.

fn seek_relative(&mut self, offset: i64) -> Result<(), Error>
