Enum Wrap 

pub enum Wrap {
    Keep,
    No,
    At(u32),
}

Prose-wrap mode.

Keep (default) and No both leave existing breaks alone; the distinction is whether the formatter is allowed to introduce new breaks later (Keep means “do nothing if already within budget”, No means “never break”). At(n) wraps at column n.

Variants

Keep

No

At(u32)

Implementations

impl Wrap

pub fn columns(self) -> u32

Effective column target. Keep and No both return u32::MAX, signalling the wrap pass “do not introduce breaks”.

pub fn shrink(self, n: u32) -> Self

Reduce the target column count by n for nested contexts whose physical lines will be prefixed (blockquote > , list-item marker, footnote indent). Keep and No are unaffected.

Trait Implementations

impl Clone for Wrap

fn clone(&self) -> Wrap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Wrap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Wrap

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Wrap

impl Eq for Wrap

impl StructuralPartialEq for Wrap
