Struct git_packetline::read::WithSidebands

pub struct WithSidebands<'a, T, F>where
    T: Read,{ /* private fields */ }

Available on crate feature blocking-io and (crate features blocking-io or async-io) only.

An implementor of BufRead yielding packet lines on each call to read_line(). It’s also possible to hide the underlying packet lines using the Read implementation which is useful if they represent binary data, like the one of a pack file.

Implementations

impl<'a, T> WithSidebands<'a, T, fn(_: bool, _: &[u8])>where T: Read,

pub fn new(parent: &'a mut StreamingPeekableIter<T>) -> Self

Create a new instance with the given provider as parent.

impl<'a, T, F> WithSidebands<'a, T, F>where T: Read, F: FnMut(bool, &[u8]),

pub fn with_progress_handler( parent: &'a mut StreamingPeekableIter<T>, handle_progress: F ) -> Self

Create a new instance with the given parent provider and the handle_progress function.

Progress or error information will be passed to the given handle_progress(is_error, text) function, with is_error: bool being true in case the text is to be interpreted as error.

pub fn without_progress_handler( parent: &'a mut StreamingPeekableIter<T> ) -> Self

Create a new instance without a progress handler.

pub fn reset_with(&mut self, delimiters: &'static [PacketLineRef<'static>])

Forwards to the parent StreamingPeekableIter::reset_with()

pub fn stopped_at(&self) -> Option<PacketLineRef<'static>>

Forwards to the parent StreamingPeekableIter::stopped_at()

pub fn set_progress_handler(&mut self, handle_progress: Option<F>)

Set or unset the progress handler.

pub fn peek_data_line(&mut self) -> Option<Result<Result<&[u8], Error>>>

Effectively forwards to the parent StreamingPeekableIter::peek_line(), allowing to see what would be returned next on a call to read_line().

Warning

This skips all sideband handling and may return an unprocessed line with sidebands still contained in it.

pub fn read_data_line( &mut self ) -> Option<Result<Result<PacketLineRef<'_>, Error>>>

Read a whole packetline from the underlying reader, with empty lines indicating a stop packetline.

Warning

This skips all sideband handling and may return an unprocessed line with sidebands still contained in it.

Trait Implementations

impl<'a, T, F> BufRead for WithSidebands<'a, T, F>where T: Read, F: FnMut(bool, &[u8]),

fn fill_buf(&mut self) -> Result<&[u8]>

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(&mut self, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to read.

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

Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided String buffer.

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

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

Check if the underlying Read has any data left to be read.

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

Read all bytes into buf until the delimiter byte or EOF is reached.

fn split(self, byte: u8) -> Split<Self>where Self: Sized,

Returns an iterator over the contents of this reader split on the byte byte.

fn lines(self) -> Lines<Self>where Self: Sized,

Returns an iterator over the lines of this reader.

impl<'a, T, F> Drop for WithSidebands<'a, T, F>where T: Read,

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, T, F> Read for WithSidebands<'a, T, F>where T: Read, F: FnMut(bool, &[u8]),

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, Global>) -> 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, appending them to buf.

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

Read 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)

Read the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

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.
