Enum SpanMode 

pub enum SpanMode {
    Disabled,
    Signposts,
}

Available on Apple only.

Controls whether tracing spans are exported as Apple signposts.

Variants

Disabled

Do not emit signpost intervals.

This avoids the per-span runtime-enabled check and is useful for applications that create spans at particularly high volume.

Signposts

Emit a signpost interval from span creation until span close.

This represents the full lifetime of a tracing span, which can include idle time and multiple enter/exit cycles, rather than only active time.

Apple signposts require a static interval name, so Rama uses the fixed name tracing-span and writes the tracing target, span name, and fields into the signpost’s dynamic message.

Trait Implementations

impl Clone for SpanMode

fn clone(&self) -> SpanMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SpanMode

impl Debug for SpanMode

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

Formats the value using the given formatter.

impl Default for SpanMode

fn default() -> SpanMode

Returns the “default value” for a type.

impl Eq for SpanMode

impl PartialEq for SpanMode

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