Struct wasmer_compiler::JumpTable

pub struct JumpTable(_);

An opaque reference to a jump table.

JumpTables are used for indirect branching and are specialized for dense, 0-based jump offsets.

Implementations

impl JumpTable

pub fn from_u32(x: u32) -> Self

Create a new instance from a u32.

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

impl JumpTable

pub fn with_number(n: u32) -> Option<Self>

Create a new jump table reference from its number.

This method is for use by the parser.

Trait Implementations

impl Archive for JumpTable where
    u32: Archive, 

type Archived = ArchivedJumpTable

The archived representation of this type.

type Resolver = JumpTableResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve(
    &self,
    pos: usize,
    resolver: Self::Resolver,
    out: *mut Self::Archived
)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for JumpTable

fn clone(&self) -> JumpTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JumpTable

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JumpTable

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

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<JumpTable, __D> for Archived<JumpTable> where
    u32: Archive,
    Archived<u32>: Deserialize<u32, __D>, 

fn deserialize(&self, deserializer: &mut __D) -> Result<JumpTable, __D::Error>

Deserializes using the given deserializer

impl Display for JumpTable

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

Formats the value using the given formatter.

impl EntityRef for JumpTable

fn new(index: usize) -> Self

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 JumpTable

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, 

Feeds a slice of this type into the given Hasher.

impl MemoryUsage for JumpTable

fn size_of_val(&self, visited: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.

impl Ord for JumpTable

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<JumpTable> for JumpTable

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

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

fn ne(&self, other: &JumpTable) -> bool

This method tests for !=.

impl PartialOrd<JumpTable> for JumpTable

fn partial_cmp(&self, other: &JumpTable) -> 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 JumpTable

fn reserved_value() -> JumpTable

Create an instance of the reserved value.

fn is_reserved_value(&self) -> bool

Checks whether value is the reserved one.

impl Serialize for JumpTable

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

Serialize this value into the given Serde serializer.

impl<__S: Fallible + ?Sized> Serialize<__S> for JumpTable where
    u32: Serialize<__S>, 

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
