Struct LoggingConfig 

pub struct LoggingConfig {
    pub filter: String,
    pub json_format: bool,
    pub target: String,
    pub ansi: bool,
    pub span_events: String,
    pub flatten_event: bool,
}

Logging and tracing configuration.

Fields

filter: String

json_format: bool

target: String

Where records are written: stdout or stderr. Anything else is a startup error.

stdout is the default and is load-bearing beyond taste: the end-to-end suite gates container readiness on server_startup appearing there.

ansi: bool

ANSI colour in the human-readable format. Ignored under json_format.

span_events: String

Span lifecycle records: none, close or full. close is the useful one — it emits a record per span as it closes, carrying the time spent busy and idle inside it.

flatten_event: bool

JSON only: lift a record’s own fields to the top level instead of nesting them under fields. What most log pipelines want, but it can collide with the format’s reserved keys, so it is not the default.
