Struct SamplingFlags 

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

W3C Trace Context sampling flags byte.

Currently only the sampled flag (bit 0) is defined by the spec.

Implementations

impl SamplingFlags

pub const SAMPLED: u8 = 0x01

The sampled flag — bit 0 of the flags byte.

pub const fn from_byte(b: u8) -> Self

Create flags from a raw byte.

pub const fn sampled() -> Self

Create flags with the sampled flag set.

pub const fn not_sampled() -> Self

Create flags with no bits set (not sampled).

pub const fn is_sampled(&self) -> bool

Returns true when the sampled flag is set.

pub const fn as_byte(&self) -> u8

Return the raw flags byte.

Trait Implementations

impl Clone for SamplingFlags

fn clone(&self) -> SamplingFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SamplingFlags

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

Formats the value using the given formatter.

impl Default for SamplingFlags

fn default() -> SamplingFlags

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SamplingFlags

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SamplingFlags

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

Formats the value using the given formatter.

impl Hash for SamplingFlags

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 SamplingFlags

fn eq(&self, other: &SamplingFlags) -> 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 Serialize for SamplingFlags

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
