Struct Slot 

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

Slots represent Variable names.

Internally, they are just a number.

Implementations

impl Slot

pub fn fresh() -> Self

Generates a fresh slot.

Any slot returned from this function has never been constructed before.

pub fn numeric(u: u32) -> Slot

Generates a numeric slot like $42

pub fn named(s: &str) -> Slot

Generates a named slot like $xyz

Trait Implementations

impl Clone for Slot

fn clone(&self) -> Slot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Slot

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

Formats the value using the given formatter.

impl Display for Slot

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

Formats the value using the given formatter.

impl Hash for Slot

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 Index<Slot> for SlotMap

type Output = Slot

The returned type after indexing.

fn index(&self, l: Slot) -> &Slot

Performs the indexing (container[index]) operation.

impl LanguageChildren for Slot

fn all_slot_occurrences_iter_mut(&mut self) -> impl Iterator<Item = &mut Slot>

fn public_slot_occurrences_iter_mut( &mut self, ) -> impl Iterator<Item = &mut Slot>

fn applied_id_occurrences_iter_mut( &mut self, ) -> impl Iterator<Item = &mut AppliedId>

fn all_slot_occurrences_iter(&self) -> impl Iterator<Item = &Slot>

fn public_slot_occurrences_iter(&self) -> impl Iterator<Item = &Slot>

fn applied_id_occurrences_iter(&self) -> impl Iterator<Item = &AppliedId>

fn to_syntax(&self) -> Vec<SyntaxElem>

fn from_syntax(elems: &[SyntaxElem]) -> Option<Self>

fn weak_shape_impl(&mut self, m: &mut (SlotMap, u32))

impl Ord for Slot

fn cmp(&self, other: &Slot) -> 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.

impl PartialEq for Slot

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

impl PartialOrd for Slot

fn partial_cmp(&self, other: &Slot) -> 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.
