Enum FieldRole 

#[non_exhaustive]
pub enum FieldRole {
    Label,
    Attribute,
    Measurement,
    TraceId,
    SpanId,
    ParentSpanId,
    TimestampNs,
    DurationNs,
    Forensic,
}

Codegen-derived classification of a field. Decoupled from the FieldKind enum so codegen can stamp this from the descriptor without re-parsing.

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.

Label

kind: LABEL.

Attribute

kind: ATTRIBUTE.

Measurement

kind: MEASUREMENT.

TraceId

kind: TRACE_ID.

SpanId

kind: SPAN_ID.

ParentSpanId

kind: PARENT_SPAN_ID.

TimestampNs

kind: TIMESTAMP_NS.

DurationNs

kind: DURATION_NS.

Forensic

kind: FORENSIC.

Trait Implementations

impl Clone for FieldRole

fn clone(&self) -> FieldRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldRole

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

Formats the value using the given formatter.

impl From<FieldKind> for FieldRole

fn from(k: FieldKind) -> Self

Converts to this type from the input type.

impl PartialEq for FieldRole

fn eq(&self, other: &FieldRole) -> 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 Copy for FieldRole

impl Eq for FieldRole
