Struct TraceId

Source
pub struct TraceId(/* private fields */);
Expand description

A 16-byte value which identifies a given trace.

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

Implementations§

Source§

impl TraceId

Helper to create trace ids for testing

Source

pub fn from_u128(num: u128) -> TraceId

Source§

impl TraceId

Source

pub const INVALID: TraceId

Invalid trace id

Source

pub const fn from_bytes(bytes: [u8; 16]) -> TraceId

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

Source

pub const fn to_bytes(self) -> [u8; 16]

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

Source

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