Trait Rewind

pub trait Rewind: ReadSite {
    // Required methods
    fn is_done(&mut self) -> Result<bool>;
    fn rewind(&mut self) -> Result<()>;
}

A reader type that can return to the beginning of the data.

Required Methods

fn is_done(&mut self) -> Result<bool>

Returns true if reader has reached the end of the data, false otherwise.

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

Positions reader at the beginning of the data.

The stream should be positioned so as to be ready to call ReadSite::read_site. In particular, the stream should be positioned past any magic number, headers, etc.
