Struct VMSharedTypeIndex

pub struct VMSharedTypeIndex(/* private fields */);

A canonicalized type index into an engine’s shared type registry.

This is canonicalized/deduped at the level of a whole engine, across all the modules loaded into that engine, not just at the level of a single particular module. This means that VMSharedTypeIndex is usable for e.g. checking that function signatures match during an indirect call (potentially to a function defined in a different module) at runtime.

Implementations

impl VMSharedTypeIndex

pub fn from_u32(x: u32) -> VMSharedTypeIndex

Create a new instance from a u32.

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

pub fn as_bits(self) -> u32

Return the raw bit encoding for this instance.

pub fn from_bits(x: u32) -> VMSharedTypeIndex

Create a new instance from the raw bit encoding.

impl VMSharedTypeIndex

pub fn new(value: u32) -> VMSharedTypeIndex

Create a new VMSharedTypeIndex.

pub fn bits(&self) -> u32

Returns the underlying bits of the index.

Trait Implementations

impl Clone for VMSharedTypeIndex

fn clone(&self) -> VMSharedTypeIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VMSharedTypeIndex

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

Formats the value using the given formatter.

impl Default for VMSharedTypeIndex

fn default() -> VMSharedTypeIndex

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VMSharedTypeIndex

fn deserialize<__D>( __deserializer: __D, ) -> Result<VMSharedTypeIndex, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EntityRef for VMSharedTypeIndex

fn new(index: usize) -> VMSharedTypeIndex

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.

impl From<VMSharedTypeIndex> for EngineOrModuleTypeIndex

fn from(i: VMSharedTypeIndex) -> EngineOrModuleTypeIndex

Converts to this type from the input type.

impl Hash for VMSharedTypeIndex

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Ord for VMSharedTypeIndex

fn cmp(&self, other: &VMSharedTypeIndex) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VMSharedTypeIndex

fn eq(&self, other: &VMSharedTypeIndex) -> 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 PartialOrd for VMSharedTypeIndex

fn partial_cmp(&self, other: &VMSharedTypeIndex) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ReservedValue for VMSharedTypeIndex

fn reserved_value() -> VMSharedTypeIndex

Create an instance of the reserved value.

fn is_reserved_value(&self) -> bool

Checks whether value is the reserved one.

impl Serialize for VMSharedTypeIndex

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
