pub struct RopeBuf { /* fields omitted */ }

Trait Implementations

impl Read for RopeBuf

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.

impl Buf for RopeBuf

fn remaining(&self) -> usize[−]

Returns the number of bytes that can be accessed from the Buf

fn bytes(&self) -> &[u8][−]

Returns a slice starting at the current Buf position and of length between 0 and Buf::remaining().

fn advance(&mut self, cnt: usize)[−]

Advance the internal cursor of the Buf

fn has_remaining(&self) -> bool[−]

Returns true if there are any more bytes to consume

fn read_slice(&mut self, dst: &mut [u8]) -> usize[−]

Read bytes from the Buf into the given slice and advance the cursor by the number of bytes read. Returns the number of bytes read.

fn read_byte(&mut self) -> Option<u8>[−]

Read a single byte from the Buf
