Struct Extensions 

pub struct Extensions(/* private fields */);

A deterministic, allocation-free set of Extensions, backed by a fixed array of 64-bit words indexed by each variant’s position in Extension::ALL.

Implementations

impl Extensions

pub const fn empty() -> Extensions

The empty set (strict CommonMark).

pub const fn from_list(list: &[Extension]) -> Extensions

The set containing exactly list. Const so presets are const values.

pub fn contains(self, ext: Extension) -> bool

Whether ext is in the set.

pub fn insert(&mut self, ext: Extension)

Adds ext to the set.

pub fn remove(&mut self, ext: Extension)

Removes ext from the set.

pub fn union(self, other: Extensions) -> Extensions

The union of this set and other.

pub fn is_empty(self) -> bool

Whether the set is empty.

pub fn iter(self) -> impl Iterator<Item = Extension>

The set’s extensions in Extension::ALL (deterministic) order.

Trait Implementations

impl Clone for Extensions

fn clone(&self) -> Extensions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Extensions

impl Debug for Extensions

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

Formats the value using the given formatter.

impl Default for Extensions

fn default() -> Extensions

Returns the “default value” for a type.

impl Eq for Extensions

impl PartialEq for Extensions

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