Struct WasmChecksum 

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

The checksum of a Wasm binary.

Allows for features requiring the exact same Wasm Module (e.g. deterministic replay) to verify that the binary used matches the one originally compiled.

Implementations

impl WasmChecksum

pub fn from_binary(bin: &[u8], recording: bool) -> WasmChecksum

Construct a WasmChecksum from the given wasm binary, used primarily for integrity checks on compiled modules when recording configs are enabled. The checksum is not computed when recording is disabled to prevent pessimization of non-recorded compilations.

Trait Implementations

impl Clone for WasmChecksum

fn clone(&self) -> WasmChecksum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmChecksum

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

Formats the value using the given formatter.

impl Default for WasmChecksum

fn default() -> WasmChecksum

Returns the “default value” for a type.

impl Deref for WasmChecksum

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for WasmChecksum

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for WasmChecksum

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

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

fn partial_cmp(&self, other: &WasmChecksum) -> 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 Serialize for WasmChecksum

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
