Struct MutableMetadata 

#[non_exhaustive]
pub struct MutableMetadata {
    pub runtime_id: String,
    pub process_tags: String,
}

The tracer metadata values that may be updated after startup.

Both fields use the same formats as the rest of the tracing stack:

• runtime_id: a runtime UUID,
• process_tags: comma-separated key:value pairs, e.g. "k1:v1,k2:v2".

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

runtime_id: String

Runtime UUID. Uniquely identifies the runtime within the host process.

process_tags: String

Comma-separated key:value process tags of the instrumented application.
