Important traits for Lines<R>

impl<R: Read> Iterator for Lines<R> type Item = Result<String>;

pub fn lines(self) -> Lines<R>

Returns an iterator over the lines of this reader.

The iterator returned from this function will yield instances of io::Result<String>. Each string returned will not have a newline byte (the 0xA byte) or CRLF (0xD, 0xA bytes) at the end.

Examples

std::io::Cursor is a type that implements BufRead. In this example, we use Cursor to iterate over all the lines in a byte slice.

use encodingbufreader::{BufReaderEncoding};
use encoding::all::UTF_8;
let bytes = "This string\nwill be read".as_bytes();

let mut lines_iter = BufReaderEncoding::new(bytes,UTF_8).map(|l| l.unwrap());
assert_eq!(lines_iter.next(), Some(String::from("This string")));
assert_eq!(lines_iter.next(), Some(String::from("will be read")));
assert_eq!(lines_iter.next(), None);

Errors

Each line of the iterator has the same error semantics as BufRead::read_line.

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

pub fn set_encoder(&mut self, encoder: EncodingRef)

Trait Implementations

impl<R> Debug for BufReaderEncoding<R> where
    R: Debug, 

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<R: Read> BufRead for BufReaderEncoding<R>

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_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<R: Read> Read for BufReaderEncoding<R>

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.

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

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, 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 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 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.
