Struct Reader

Source
pub struct Reader<'a>(pub &'a [u8]);
Expand description

Wrapper around utf-8 encoded text. This is defined as a tuple struct to allow pattern matching on it via byte literals (for example text::Reader(b"hello")).

Implementations§

Source§

impl<'a> Reader<'a>

Source

pub fn len(&self) -> usize
