Trait Read 

pub trait Read {
    // Required method
    fn read(&self, buf: &mut [u8], offset: usize) -> Result<usize, Error>;
}

To make a lazy reader cursor from scratch, this trait must be implemented. See Cursor::new about how to create a cursor based on this trait.

Required Methods

fn read(&self, buf: &mut [u8], offset: usize) -> Result<usize, Error>

Pull some bytes from this source into the specified buffer with offset, returning how many bytes were read.

Implementors

impl Read for Vec<u8>
