Struct cranelift_codegen::ir::entities::Table

pub struct Table(_);

An opaque reference to a WebAssembly table.

Tables are used to store a list of function references. They can be created with FuncEnvironment::make_table. They can be used with FuncEnvironment::translate_call_indirect.

While the order is stable, it is arbitrary.

Implementations

impl Table

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 Table

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

Create a new table reference from its number.

This method is for use by the parser.

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Table

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

Formats the value using the given formatter.

impl Display for Table

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

Formats the value using the given formatter.

impl EntityRef for Table

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 From<Table> for AnyEntity

fn from(r: Table) -> Self

Converts to this type from the input type.

impl Hash for Table

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 Ord for Table

fn cmp(&self, other: &Table) -> 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<Table> for Table

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

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

fn reserved_value() -> Table

Create an instance of the reserved value.

fn is_reserved_value(&self) -> bool

Checks whether value is the reserved one.

impl Copy for Table

impl Eq for Table

impl StructuralEq for Table

impl StructuralPartialEq for Table
