Struct MarkSet 

pub struct MarkSet { /* private fields */ }

Set of marks active at a single character position.

Implementations

impl MarkSet

pub fn new() -> Self

Empty set.

pub fn contains(&self, name: &str) -> bool

Is name set (boolean or valued)?

pub fn value_of(&self, name: &str) -> Option<&str>

String value for a valued mark, or None if absent or boolean.

pub fn iter(&self) -> impl Iterator<Item = &str> + '_

Iterate over active mark names in lexicographic order.

pub fn iter_with_values(&self) -> impl Iterator<Item = (&str, &MarkValue)> + '_

Iterate over (name, MarkValue) pairs.

pub fn iter_booleans(&self) -> impl Iterator<Item = &str> + '_

Iterate over only boolean-style marks.

pub fn iter_values(&self) -> impl Iterator<Item = (&str, &str)> + '_

Iterate over only valued marks as (name, value) pairs.

pub fn len(&self) -> usize

Number of active marks.

pub fn is_empty(&self) -> bool

Is the set empty?

Trait Implementations

impl Clone for MarkSet

fn clone(&self) -> MarkSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MarkSet

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

Formats the value using the given formatter.

impl Default for MarkSet

fn default() -> MarkSet

Returns the “default value” for a type.

impl PartialEq for MarkSet

fn eq(&self, other: &MarkSet) -> 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.
