Struct Fences 

struct Fences {
    open: Option<(char, usize)>,
}

Tracks fenced code blocks line by line, so every rewrite in this module agrees on where a fence is.

A fence follows CommonMark: at most three spaces of indentation, then a run of at least three backticks or tildes (a backtick fence’s info string has no backtick). It closes on a run of the same character at least as long, with nothing after it. A line indented four spaces is indented code, never a fence.

Fields

open: Option<(char, usize)>

The open fence’s character and run length.

Implementations

impl Fences

fn line(&mut self, line: &str) -> bool

Feeds the next line and reports whether it is fenced; the fence lines themselves count as fenced.

Trait Implementations

impl Default for Fences

fn default() -> Fences

Returns the “default value” for a type.
