Struct tracing::span::Id

source · [−]

pub struct Id(_);

Expand description

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

source

impl Id

source

pub fn from_u64(u: u64) -> Id

Constructs a new span ID from the given u64.

    Note: Span IDs must be greater than zero.

Panics

If the provided u64 is 0.

source

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

Constructs a new span ID from the given NonZeroU64.

Unlike Id::from_u64, this will never panic.

source

pub fn into_u64(&self) -> u64

Returns the span’s ID as a u64.

source

pub const fn into_non_zero_u64(&self) -> NonZeroU64

Returns the span’s ID as a NonZeroU64.
