[−][src]Struct tokio_trace::span::Id
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.
Methods
impl Id
[src]
pub fn from_u64(u: u64) -> Id
[src]
Constructs a new span ID from the given u64
.
Note: Span IDs must be greater than zero.
Panics
- If the provided
u64
is 0
pub fn into_u64(&self) -> u64
[src]
Returns the span's ID as a u64
.
