Struct `Id`

struct Id(_)

Identifies a span within the context of a subscriber.

They are generated by Subscribers 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`

fn from_u64(u: u64) -> Self

Constructs a new span ID from the given u64.

    Note: Span IDs must be greater than zero.

Panics

If the provided u64 is 0.

const fn from_non_zero_u64(id: NonZeroU64) -> Self

Constructs a new span ID from the given NonZeroU64.

Unlike Id::from_u64, this will never panic.

fn into_u64(self: &Self) -> u64

Returns the span's ID as a u64.

const fn into_non_zero_u64(self: &Self) -> NonZeroU64

Returns the span's ID as a NonZeroU64.
