Struct InferenceVar 

pub struct InferenceVar(pub u32);

An inference variable representing an unknown type. These are created when instantiating generic functions.

Tuple Fields

0: u32

Trait Implementations

impl Clone for InferenceVar

fn clone(&self) -> InferenceVar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InferenceVar

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

Formats the value using the given formatter.

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 PartialEq for InferenceVar

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

type Value = InferenceInfo

fn index(&self) -> u32

fn from_index(u: u32) -> Self

fn tag() -> &'static str

fn order_roots( a: Self, a_value: &Self::Value, b: Self, b_value: &Self::Value, ) -> Option<(Self, Self)>

You should return first the key that should be used as root, then the other key (that will then point to the new root).
