Struct ImportKindSet

pub struct ImportKindSet { /* private fields */ }

A deterministically ordered set of ImportKind values.

Implementations

impl ImportKindSet

pub const fn new() -> Self

Creates an empty set.

pub fn with(self, kind: ImportKind) -> Self

Returns a set containing kind in addition to the existing values.

pub fn contains(&self, kind: ImportKind) -> bool

Returns whether kind is present.

pub fn len(&self) -> usize

Returns the number of different syntax kinds in the set.

pub fn is_empty(&self) -> bool

Returns whether the set contains no syntax kinds.

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

Iterates over kinds in their stable declaration order.

Trait Implementations

impl Clone for ImportKindSet

fn clone(&self) -> ImportKindSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImportKindSet

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

Formats the value using the given formatter.

impl Default for ImportKindSet

fn default() -> ImportKindSet

Returns the “default value” for a type.

impl Display for ImportKindSet

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

Formats the value using the given formatter.

impl From<ImportKind> for ImportKindSet

fn from(kind: ImportKind) -> Self

Converts to this type from the input type.

impl FromIterator<ImportKind> for ImportKindSet

fn from_iter<T: IntoIterator<Item = ImportKind>>(kinds: T) -> Self

Creates a value from an iterator.

impl Hash for ImportKindSet

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoIterator for &'a ImportKindSet

type Item = ImportKind

The type of the elements being iterated over.

type IntoIter = Copied<Iter<'a, ImportKind>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for ImportKindSet

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