Struct WhnfCacheKey 

pub struct WhnfCacheKey {
    pub expr_hash: u64,
}

A cache key for memoizing WHNF results.

Fields

expr_hash: u64

Structural hash of the input expression.

Implementations

impl WhnfCacheKey

pub fn from_expr(expr: &Expr) -> Self

Compute a cache key from an expression.

Trait Implementations

impl Clone for WhnfCacheKey

fn clone(&self) -> WhnfCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhnfCacheKey

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

Formats the value using the given formatter.

impl Hash for WhnfCacheKey

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 WhnfCacheKey

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