Struct chalk_ir::InferenceVar

pub struct InferenceVar {
    pub(crate) index: u32,
}

A type, lifetime or constant whose value is being inferred.

Fields

index: u32

Implementations

impl InferenceVar

pub fn index(self) -> u32

Gets the underlying index value.

pub fn to_ty<I: Interner>(self, interner: I, kind: TyVariableKind) -> Ty<I>

Wraps the inference variable in a type.

pub fn to_lifetime<I: Interner>(self, interner: I) -> Lifetime<I>

Wraps the inference variable in a lifetime.

pub fn to_const<I: Interner>(self, interner: I, ty: Ty<I>) -> Const<I>

Wraps the inference variable in a constant.

Trait Implementations

impl Clone for InferenceVar

fn clone(&self) -> InferenceVar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InferenceVar

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

Formats the value using the given formatter.

impl From<u32> for InferenceVar

fn from(index: u32) -> InferenceVar

Converts to this type from the input type.

impl Hash for InferenceVar

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 InferenceVar

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<InferenceVar> for InferenceVar

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<InferenceVar> for InferenceVar

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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