Struct Chunker 

pub struct Chunker { /* private fields */ }

Chunk Generator given an input stream. Do not use directly. Use chunk_target_default.

Implementations

impl Chunker

pub fn new(target_chunk_size: usize) -> Self

pub fn next_boundary(&mut self, data: &[u8]) -> Option<usize>

Looks for the next chunk boundary in the data. Assumes that whatever is in the current state has been prepended to the current data. If a boundary cannot be found based on the current amount of data, then None is returned.

pub fn next(&mut self, data: &[u8], is_final: bool) -> (Option<Chunk>, usize)

Process more data; this is a continuation of any data from before when calls were

Returns the next chunk, if available, and the amount of data that was digested.

If is_final is true, then it is assumed that no more data after this block will come, and any data currently present and at the end will be put into a final chunk.

pub fn next_block(&mut self, data: &[u8], is_final: bool) -> Vec<Chunk>

Keeps chunking until no more chunks can be reliably produced, returning a vector of the resulting chunks.

pub fn next_block_bytes(&mut self, data: &Bytes, is_final: bool) -> Vec<Chunk>

Keeps chunking until no more chunks can be reliably produced, returning a vector of the resulting chunks.

The data is inserted here as a Bytes object, which means that no copying of the data is performed except at the boundaries. The resulting chunks then end up each holding a reference to the original data object, which will not be deallocated until all the original bytes are gone.

pub fn finish(&mut self) -> Option<Chunk>

Trait Implementations

impl Default for Chunker

fn default() -> Self

Returns the “default value” for a type.
