Struct wasmtime_environ::SignatureIndex

pub struct SignatureIndex(_);

Index type of a signature (imported or defined) inside the WebAssembly module.

Implementations

impl SignatureIndex

pub fn from_u32(x: u32) -> SignatureIndex

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) -> SignatureIndex

Create a new instance from the raw bit encoding.

Trait Implementations

impl Clone for SignatureIndex

fn clone(&self) -> SignatureIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureIndex

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SignatureIndex

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

Deserialize this value from the given Serde deserializer.

impl EntityRef for SignatureIndex

fn new(index: usize) -> SignatureIndex

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 Hash for SignatureIndex

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 Index<SignatureIndex> for ModuleTypes

type Output = WasmFuncType

The returned type after indexing.

fn index(&self, sig: SignatureIndex) -> &WasmFuncType

Performs the indexing (container[index]) operation.

impl Ord for SignatureIndex

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SignatureIndex> for SignatureIndex

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

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl ReservedValue for SignatureIndex

fn reserved_value() -> SignatureIndex

Create an instance of the reserved value.

fn is_reserved_value(&self) -> bool

Checks whether value is the reserved one.

impl Serialize for SignatureIndex

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.
