Struct SpanId 

pub struct SpanId { /* private fields */ }

Unique Span identifier.

Wraps a tracing::span::Id with a suitable parser.

Display and FromStr are guaranteed to round-trip.

Implementations

impl SpanId

pub fn meta_field_name() -> &'static str

Metadata field name associated with SpanId values.

Trait Implementations

impl Clone for SpanId

fn clone(&self) -> SpanId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpanId

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

Formats the value using the given formatter.

impl Display for SpanId

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

Formats the value using the given formatter.

impl FromStr for SpanId

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a Span Id from a hex value.

type Err = ParseSpanIdError

The associated error which can be returned from parsing.

impl Hash for SpanId

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 SpanId

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