Struct HeadingLevel

Source 
pub struct HeadingLevel(/* private fields */);
Available on crate features html and matrix only.
Expand description

The level of a heading element.

The supported levels range from 1 (highest) to 6 (lowest). Other levels cannot construct this and do not use the MatrixElement::H variant.

Implementations§

Source§

impl HeadingLevel

Source

pub fn value(&self) -> u8

Source§

impl PartialEq<u8> for HeadingLevel

Source§

fn eq(&self, other: &u8) -> bool
