Variants

SizeOf

Returns the size of a value of that type.

AlignOf

Returns the minimum alignment of a type.

OffsetOf(Vec<(VariantIdx, FieldIdx)>)

Returns the offset of a field.

UbCheck(UbKind)

cfg!(debug_assertions), but at codegen time

Trait Implementations

impl Clone for NullOp

fn clone(&self) -> NullOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NullOp

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

Formats the value using the given formatter.

impl PartialEq for NullOp

fn eq(&self, other: &NullOp) -> 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 Eq for NullOp

impl StructuralPartialEq for NullOp

Layout

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.
