Enum CallsiteSource 

#[non_exhaustive]
#[repr(u8)]
pub enum CallsiteSource {
    TracingEvent = 1,
    TracingSpan = 2,
    Forensic = 3,
    Instrument = 4,
}

Callsite source — drives both human display and the BLAKE3 input. Spec 31 § 3.4 enum.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TracingEvent = 1

Tracing event (Direction A bridge).

TracingSpan = 2

Tracing span (Direction A bridge, ObsSpanCompleted).

Forensic = 3

obs::forensic! macro.

Instrument = 4

#[obs::instrument]-emitted ObsFnEntered/ObsFnExited.

Implementations

impl CallsiteSource

pub const fn as_str(&self) -> &'static str

Human-readable identifier; matches the CLI render in spec 31 § 5.4.

Trait Implementations

impl Clone for CallsiteSource

fn clone(&self) -> CallsiteSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallsiteSource

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

Formats the value using the given formatter.

impl Hash for CallsiteSource

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 CallsiteSource

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