Struct HideSet 

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

An interned set of macro names.

Only meaningful together with the HideSets table it was created by. There is one table per translation unit, so mixing two of them is a bug rather than a case to handle.

Implementations

impl HideSet

pub const EMPTY: HideSet

The empty set, which is index zero in every table.

Available as a constant because a token that came straight from the lexer has an empty hide set and building one should not need the table.

pub const fn is_empty(self) -> bool

Whether this is the empty set.

pub const fn raw(self) -> u32

The underlying index, for packing a hide set into a token.

Trait Implementations

impl Clone for HideSet

fn clone(&self) -> HideSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HideSet

impl Debug for HideSet

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

Formats the value using the given formatter.

impl Eq for HideSet

impl Hash for HideSet

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 Ord for HideSet

fn cmp(&self, other: &HideSet) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for HideSet

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for HideSet

fn partial_cmp(&self, other: &HideSet) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
