Struct JumpTable

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

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,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

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.

fn resolve(&self, resolver: Self::Resolver, out: Place<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 duplicate of the value.

const 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<__D: Fallible + ?Sized> Deserialize<JumpTable, __D> for Archived<JumpTable>

where u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<JumpTable, <__D as Fallible>::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, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

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 JumpTable

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

Tests for self and other values to be equal, and is used by ==.

const 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 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

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 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<__S: Fallible + ?Sized> Serialize<__S> for JumpTable

where u32: Serialize<__S>,

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

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