Struct opentelemetry_api::trace::TraceFlags

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

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

impl TraceFlags

pub const SAMPLED: TraceFlags = _

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.

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

Construct new trace flags

pub fn is_sampled(&self) -> bool

Returns true if the sampled flag is set

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

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

pub fn to_u8(self) -> u8

Returns the flags as a u8

Trait Implementations

impl BitAnd for TraceFlags

type Output = TraceFlags

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitOr for TraceFlags

type Output = TraceFlags

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for TraceFlags

fn clone(&self) -> TraceFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraceFlags

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

Formats the value using the given formatter.

impl Default for TraceFlags

fn default() -> TraceFlags

Returns the “default value” for a type.

impl Hash for TraceFlags

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 LowerHex for TraceFlags

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

Formats the value using the given formatter.

impl Not for TraceFlags

type Output = TraceFlags

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for TraceFlags

fn eq(&self, other: &TraceFlags) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
