Enum NullOp 

pub enum NullOp {
    OffsetOf(Vec<(VariantIdx, FieldIdx)>),
    UbChecks,
    ContractChecks,
}

Variants

OffsetOf(Vec<(VariantIdx, FieldIdx)>)

Returns the offset of a field.

UbChecks

cfg!(ub_checks), but at codegen time

ContractChecks

cfg!(contract_checks), but at codegen time

Trait Implementations

impl Clone for NullOp

fn clone(&self) -> NullOp

Returns a duplicate 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 Hash for NullOp

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 NullOp

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

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.
