Struct nue_io::SeekForwardRead

pub struct SeekForwardRead<T> { /* fields omitted */ }

A forward seeking wrapper around a Read type.

Methods

impl<T> SeekForwardRead<T>

fn new(inner: T) -> Self

Creates a new SeekForwardRead.

Trait Implementations

impl<T: Read> SeekForward for SeekForwardRead<T>

fn seek_forward(&mut self, offset: u64) -> Result<u64>

Seeks forward in the stream.

impl<T: SeekRewind> SeekRewind for SeekForwardRead<T>

fn seek_rewind(&mut self) -> Result<()>

Seeks back to the beginning of the stream.

impl<T: Tell> Tell for SeekForwardRead<T>

fn tell(&mut self) -> Result<u64>

Returns the current absolute position in the stream.

impl<T: SeekAbsolute> SeekAbsolute for SeekForwardRead<T>

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

Seeks to the specified position in the stream.

impl<T: SeekEnd> SeekEnd for SeekForwardRead<T>

fn seek_end(&mut self, offset: i64) -> Result<u64>

Seeks to the end of the stream + offset.

impl<T: SeekBackward> SeekBackward for SeekForwardRead<T>

fn seek_backward(&mut self, offset: u64) -> Result<u64>

Seeks backward in the stream.

impl<T: BufRead> BufRead for SeekForwardRead<T>

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

Fills the internal buffer of this object, returning the buffer contents.

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

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

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

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

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

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

fn lines(self) -> Lines<Self>

Returns an iterator over the lines of this reader.

impl<T: Read> Read for SeekForwardRead<T>

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.
