Struct std::io::util::LimitReader[src]

pub struct LimitReader<R> {
    // some fields omitted
}

Wraps a Reader, limiting the number of bytes that can be read from it.

Methods

impl<R: Reader> LimitReader<R>

fn new(r: R, limit: uint) -> LimitReader<R>

Creates a new LimitReader

fn unwrap(self) -> R

Consumes the LimitReader, returning the underlying Reader.

fn limit(&self) -> uint

Returns the number of bytes that can be read before the LimitReader will return EOF.

Note

The reader may reach EOF after reading fewer bytes than indicated by this method if the underlying reader reaches EOF.
