Struct CaseInsensitiveKeywordSet

pub struct CaseInsensitiveKeywordSet(FastHashSet<AsciiUniCase<&'static str>>);

A case-insensitive, ASCII-only set of strings, for use with Namer to avoid collisions with keywords and other reserved identifiers.

This is currently implemented as a hash table. Future versions of Naga may change the implementation based on speed and code size considerations.

Implementations

impl CaseInsensitiveKeywordSet

pub fn new() -> Self

Returns a new mutable empty set.

pub fn empty() -> &'static Self

Returns a reference to the empty set.

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

Returns whether the set contains the given string, with comparison by str::eq_ignore_ascii_case().

Trait Implementations

impl Clone for CaseInsensitiveKeywordSet

fn clone(&self) -> CaseInsensitiveKeywordSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaseInsensitiveKeywordSet

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

Formats the value using the given formatter.

impl Default for &'static CaseInsensitiveKeywordSet

fn default() -> Self

Returns the “default value” for a type.

impl Default for CaseInsensitiveKeywordSet

fn default() -> CaseInsensitiveKeywordSet

Returns the “default value” for a type.

impl<'a> Extend<&'a &'static str> for CaseInsensitiveKeywordSet

Accepts double references so that .extend(&["foo"]) works.

fn extend<T: IntoIterator<Item = &'a &'static str>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl Extend<&'static str> for CaseInsensitiveKeywordSet

fn extend<T: IntoIterator<Item = &'static str>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl<'a> FromIterator<&'a &'static str> for CaseInsensitiveKeywordSet

Accepts double references so that CaseInsensitiveKeywordSet::from_iter(&["foo"]) works.

fn from_iter<T: IntoIterator<Item = &'a &'static str>>(iter: T) -> Self

Creates a value from an iterator.

impl FromIterator<&'static str> for CaseInsensitiveKeywordSet

fn from_iter<T: IntoIterator<Item = &'static str>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for CaseInsensitiveKeywordSet

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