Struct opentelemetry::trace::TraceFlags

source · [−]

pub struct TraceFlags(_);

Available on crate feature trace only.

Expand description

Flags that can be set on a SpanContext.

The current version of the specification only supports a single flag TraceFlags::SAMPLED.

See the W3C TraceContext specification’s trace-flags section for more details.

Implementations

source

impl TraceFlags

source

pub const SAMPLED: TraceFlags = TraceFlags(1)

Trace flags with the sampled flag set to 1.

Spans that are not sampled will be ignored by most tracing tools. See the sampled section of the W3C TraceContext specification for details.

source

pub const fn new(flags: u8) -> TraceFlags

Construct new trace flags

source

pub fn is_sampled(&self) -> bool

Returns true if the sampled flag is set

source

pub fn with_sampled(&self, sampled: bool) -> TraceFlags

Returns copy of the current flags with the sampled flag set.

source

pub fn to_u8(self) -> u8

Returns the flags as a u8
