Struct holochain::prelude::kitsune_p2p::dependencies::kitsune_p2p_types::dependencies::ghost_actor::dependencies::tracing::field::Field
pub struct Field { /* private fields */ }
Expand description
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.
