Struct smbioslib::io::Empty1.0.0[][src]

pub struct Empty { /* fields omitted */ }

A reader which is always at EOF.

This struct is generally created by calling empty(). Please see the documentation of empty() for more details.

Trait Implementations

impl BufRead for Empty[src]

    byte: u8,
    buf: &mut Vec<u8, Global>
) -> Result<usize, Error>
[src]

Read all bytes into buf until the delimiter byte or EOF is reached. Read more

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

Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided buffer. Read more

fn split(self, byte: u8) -> Split<Self>

Notable traits for Split<B>

impl<B> Iterator for Split<B> where
