Struct TraceId

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

A 128-bit UUID identifying a trace. All spans caused by the same originating span share the same trace ID.

Implementations

impl TraceId

pub fn random<R: Rng>(rng: &mut R) -> Self

Returns a random trace ID that can be assumed to be globally unique if rng generates actually-random numbers.

Trait Implementations

impl Clone for TraceId

fn clone(&self) -> TraceId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceId

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

Formats the value using the given formatter.

impl Default for TraceId

fn default() -> TraceId

Returns the “default value” for a type.

impl Display for TraceId

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

Formats the value using the given formatter.

impl Hash for TraceId

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 PartialEq for TraceId

fn eq(&self, other: &TraceId) -> 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.
