Struct SpanId 

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

Unique identifier for a profiling span.

Used to track hierarchical spans for flame graph generation. Drivers use this to correlate enter() and exit() calls.

Implementations

impl SpanId

pub fn new() -> Self

Create a new unique span ID.

IDs are globally unique within a process (uses atomic counter).

pub const fn null() -> Self

Null span ID (represents no parent or inactive span).

pub const fn is_null(&self) -> bool

Check if this is the null span.

pub const fn as_u64(&self) -> u64

Get the raw ID value.

Trait Implementations

impl Clone for SpanId

fn clone(&self) -> SpanId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpanId

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

Formats the value using the given formatter.

impl Default for SpanId

fn default() -> Self

Returns the “default value” for a type.

impl Hash for SpanId

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 SpanId

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