Struct diffusion::FileReader

pub struct FileReader<T> where T: Read {
    // some fields omitted
}

Methods

impl<T> FileReader<T> where T: Read

fn new(file: T) -> Result<FileReader<T>>

returns a new instance of FileReader. It returns error if the file is found corrupted.

impl<T> Reader for FileReader<T> where T: Read

fn read(&mut self) -> Result<Option<Vec<u8>>>
