Struct librsync::Patch

pub struct Patch<'a, B: 'a, D> { /* fields omitted */ }

A struct to apply a delta to a basis file, to recreate the new file.

This type takes a Read + Seek stream for the base file, and a Read stream for the delta file. It then provides another Read stream from which get the resulting patched file.

Methods

impl<'a, B: Read + Seek + 'a, D: Read> Patch<'a, B, BufReader<D>>

fn new(base: B, delta: D) -> Result<Self>

Creates a new patch stream.

This constructor takes a Read + Seek stream for the basis file (base parameter), and a Read stream for the delta file (delta parameter). It produces a stream from which read the resulting patched file.

impl<'a, B: Read + Seek + 'a, D: BufRead> Patch<'a, B, D>

fn with_buf_read(base: B, delta: D) -> Result<Self>

Creates a new patch stream by using a BufRead as delta stream.

This constructor specializes the new constructor by taking a BufRead instance as delta parameter. Prefer this constructor if you already have a BufRead as input stream, since it avoids wrapping the input stream into another BufRead instance. See new constructor for more details on the parameters.

fn into_inner(self) -> (B, D)

Unwraps this stream and returns the underlying streams.

Trait Implementations

impl<'a, B, D: BufRead> Read for Patch<'a, B, D>

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

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

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

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

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

Read the exact number of bytes required to fill buf.

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

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

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

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

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

Creates an adaptor which will chain this stream with another.

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

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