Variants§

§

Add

The + operator (addition)

§

Sub

The - operator (subtraction)

§

Mul

The * operator (multiplication)

§

Div

The / operator (division)

Division by zero is UB, because the compiler should have inserted checks prior to this.

§

Rem

The % operator (modulus)

Using zero as the modulus (second operand) is UB, because the compiler should have inserted checks prior to this.

§

BitXor

The ^ operator (bitwise xor)

§

BitAnd

The & operator (bitwise and)

§

BitOr

The | operator (bitwise or)

§

Shl

The << operator (shift left)

The offset is truncated to the size of the first operand before shifting.

§

Shr

The >> operator (shift right)

The offset is truncated to the size of the first operand before shifting.

§

Eq

The == operator (equality)

§

Lt

The < operator (less than)

§

Le

The <= operator (less than or equal to)

§

Ne

The != operator (not equal to)

§

Ge

The >= operator (greater than or equal to)

§

Gt

The > operator (greater than)

§

source§

default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous).

source§

default fn recover( _: Tcx, _: &DepNode<<Tcx as DepContext>::DepKind> ) -> Option<T>

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
