Struct lineriver::linereader::LineReader

pub struct LineReader<R> { /* private fields */ }

Buffered non-blocking reader that returns only complete lines.

Implementations

impl<R: Read + AsRawFd + Debug> LineReader<R>

pub fn new(reader: R) -> Result<Self, Error>

Creates a new LineReader, setting the underlying descriptor as non-blocking.

impl<R: Read + Debug> LineReader<R>

pub fn from_nonblocking(reader: R) -> Result<Self, Error>

Creates a new LineReader.

Assumes the reader is already non-blocking, not configuring anything in the underlying descriptor.

Trait Implementations

impl<R: AsFd> AsFd for LineReader<R>

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl<R: AsRawFd> AsRawFd for LineReader<R>

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl<R: Debug> Debug for LineReader<R>

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

Formats the value using the given formatter.

impl<R: Read + Debug> LineRead for LineReader<R>

fn eof(&self) -> bool

Returns true if we have already reached EOF in the underlying Read object.

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

Performs a single read operation on the underlying Read object.

fn lines_get(&mut self) -> Vec<String>

Returns the internal line buffer.

fn has_lines(&mut self) -> bool

Returns true if there are complete lines in the internal buffer.

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

Reads all available data into the internal line buffer, or at least until a complete line is available.
