Struct fluvio_future::tracing::field::Field[−][src]

pub struct Field { /* fields omitted */ }

An opaque key allowing O(1) access to a field in a Span’s key-value data.

As keys are defined by the metadata of a span, rather than by an individual instance of a span, a key may be used to access the same field across all instances of a given span with the same metadata. Thus, when a subscriber observes a new span, it need only access a field by name once, and use the key for that name for all other accesses.

Implementations

impl Field[src]

pub fn callsite(&self) -> Identifier[src]

Returns an Identifier that uniquely identifies the Callsite which defines this field.

pub fn name(&self) -> &'static str[src]

Returns a string representing the name of the field.
