Struct stdio::StdioReader

pub struct StdioReader { /* private fields */ }

A reader to stdio buffers.

Implementations

impl StdioReader

pub fn lock(&self) -> StdioReadGuard<'_>

Lock the reader and return a guard that can perform reading operation to that buffer. Note that this lock does not lock the underlying ring buffer. It only excludes other readr from performing simultaneous read, but does not prevent a writer to perform writing to the underlying ring buffer.

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

Read a line from the ring buffer and return. Remaining bytes are stored in the inner buffer. Do NOT use this function alternatively with read() method defined in StdioReadGuard. This function returns the number of bytes read. It will return zero only upon EOF.

Trait Implementations

impl Clone for StdioReader

fn clone(&self) -> StdioReader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
