Trait LineStream 

pub trait LineStream<'a> {
    // Required methods
    fn next_line(&mut self) -> Option<&'a str>;
    fn peek_line(&mut self) -> Option<&'a str>;

    // Provided method
    fn remainder_is_whitespace(&mut self) -> bool { ... }
}

Line source with peek for section detection (blank-line separators).

Implemented by the memchr cursor on the hot iterator path and by Peekable<I> for tests / ad-hoc callers.

Required Methods

fn next_line(&mut self) -> Option<&'a str>

fn peek_line(&mut self) -> Option<&'a str>

Provided Methods

fn remainder_is_whitespace(&mut self) -> bool

True when every remaining line, including the current peek, is empty or whitespace. Default is false so a one-line peek cannot hide a following section.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
