Struct ComponentPC 

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

A Wasm bytecode offset relative to the start of a component (or top-level module) binary.

When compiling a component, the Wasm parser returns source positions relative to the entire component binary. This type captures that convention. Use ComponentPC::to_module_pc to convert to a ModulePC given the byte offset of the module within the component.

Implementations

impl ComponentPC

pub fn new(offset: u32) -> Self

Create a new component-relative PC from a raw offset.

pub fn raw(self) -> u32

Get the raw u32 offset.

pub fn to_module_pc(self, wasm_module_offset: u64) -> ModulePC

Convert to a module-relative PC by subtracting the byte offset of the module within the component binary.

Trait Implementations

impl Clone for ComponentPC

fn clone(&self) -> ComponentPC

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentPC

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

Formats the value using the given formatter.

impl Display for ComponentPC

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

Formats the value using the given formatter.

impl Hash for ComponentPC

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 ComponentPC

fn cmp(&self, other: &ComponentPC) -> 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 ComponentPC

fn eq(&self, other: &ComponentPC) -> 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 ComponentPC

fn partial_cmp(&self, other: &ComponentPC) -> 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.
