Struct SpanId 

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

W3C Trace Context span ID (64-bit / 8 bytes).

Identifies a specific span within a trace. Formatted as 16 lowercase hex characters per the W3C specification.

Invariants

• An all-zero span ID is considered invalid (per W3C spec).

Examples

use torvyn_types::SpanId;

let id = SpanId::new([0x00, 0xf0, 0x67, 0xaa, 0x0b, 0xa9, 0x02, 0xb7]);
assert!(id.is_valid());
assert_eq!(id.to_string().len(), 16);

Implementations

impl SpanId

pub const fn new(bytes: [u8; 8]) -> Self

Create a new SpanId from raw bytes.

WARM PATH — called per span creation.

pub const fn as_bytes(&self) -> &[u8; 8]

Returns the raw bytes.

pub fn is_valid(&self) -> bool

Returns true if this span ID is valid (non-zero per W3C spec).

pub const fn invalid() -> Self

Returns an invalid (all-zero) span ID.

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<'de> Deserialize<'de> for SpanId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SpanId

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

Formats the value using the given formatter.

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.

impl Serialize for SpanId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
