Struct EVar

pub struct EVar {
    cx: EVarCxId,
    id: EVid,
}

An existential varriable is identified by a context and an id. Two evars are considered equal if both the context and id are equal.

Fields

cx: EVarCxId

id: EVid

Implementations

impl EVar

pub fn cx(&self) -> EVarCxId

Trait Implementations

impl Clone for EVar

fn clone(&self) -> EVar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EVar

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for EVar

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for EVar

fn encode(&self, __encoder: &mut __E)

impl Hash for EVar

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 EVar

fn cmp(&self, other: &EVar) -> 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 EVar

fn eq(&self, other: &EVar) -> 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 EVar

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

impl Pretty for EVar

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

fn default_cx(tcx: TyCtxt<'_>) -> PrettyCx<'_>
