Struct tracing::span::Id[][src]

pub struct Id(_);

Identifies a span within the context of a collector.

They are generated by collectors for each span as it is created, by the new_span trait method. See the documentation for that method for more information on span ID generation.

Implementations

impl Id[src]

pub fn from_u64(u: u64) -> Id[src]

Constructs a new span ID from the given u64.

Note
Note: Span IDs must be greater than zero.

Panics

  • If the provided u64 is 0

pub const fn from_non_zero_u64(id: NonZeroU64) -> Id[src]

Constructs a new span ID from the given NonZeroU64.

Unlike Id::from_u64, this will never panic.

pub fn into_u64(&self) -> u64[src]

Returns the span’s ID as a u64.

pub const fn into_non_zero_u64(&self) -> NonZeroU64[src]

Returns the span’s ID as a NonZeroU64.
