Struct tracing_core::span::Id [−][src]
Identifies a span within the context of a subscriber.
They are generated by Subscriber
s 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) -> Self
[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) -> Self
[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
.
