Struct opentelemetry::trace::SpanId

source ·
pub struct SpanId(/* private fields */);
Expand description

An 8-byte value which identifies a given span.

The id is valid if it contains at least one non-zero byte.

Implementations§

source§

impl SpanId

source

pub const INVALID: SpanId = _

Invalid span id

source

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

Create a span id from its representation as a byte array.

source

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

Return the representation of this span id as a byte array.

source

pub fn from_hex(hex: &str) -> Result<Self, ParseIntError>

Converts a string in base 16 to a span id.

§Examples
use opentelemetry::trace::SpanId;

assert!(SpanId::from_hex("42").is_ok());
assert!(SpanId::from_hex("58406520a0066491").is_ok());

assert!(SpanId::from_hex("not_hex").is_err());
