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.

§

UbChecks

cfg!(ub_checks), but at codegen time

Trait Implementations§

impl Clone for NullOp

source§

fn clone(&self) -> NullOp

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl Debug for NullOp

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

Formats the value using the given formatter. Read more
source§

impl PartialEq for NullOp

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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.
