Struct ExecutionId

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

An Id uniquely identifying an execution.

An ExecutionId should never be re-used as it’s used to collect metadata about the execution and to generate TraceIds which need to be globally unique.

Implementations

impl ExecutionId

pub fn random(rng: &mut impl Rng) -> ExecutionId

Uses a random generator to generate the ExecutionId.

pub const fn from_raw(raw: u128) -> ExecutionId

Creates an ExecutionId from a raw value, extra care needs to be taken that this is not a constant value or re-used in any way.

When possible prefer using ExecutionId::random.

Methods from Deref<Target = u128>

pub const MIN: u128 = 0u128

pub const MAX: u128 = 340_282_366_920_938_463_463_374_607_431_768_211_455u128

pub const BITS: u32 = 128u32

Trait Implementations

impl Clone for ExecutionId

fn clone(&self) -> ExecutionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionId

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

Formats the value using the given formatter.

impl Default for ExecutionId

fn default() -> ExecutionId

Returns the “default value” for a type.

impl Deref for ExecutionId

type Target = u128

The resulting type after dereferencing.

fn deref(&self) -> &<ExecutionId as Deref>::Target

Dereferences the value.

impl<'de> Deserialize<'de> for ExecutionId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ExecutionId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 PartialEq for ExecutionId

fn eq(&self, other: &ExecutionId) -> 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 Serialize for ExecutionId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
