Struct LogContextConfig 

pub struct LogContextConfig { /* private fields */ }

Parsed log-context template (Java LogContextConfig) — the application’s app-log-context.yaml when present, otherwise the built-in default.

Implementations

impl LogContextConfig

pub fn instance() -> &'static LogContextConfig

The lazily-loaded singleton; touching AppConfigReader first guarantees ${ENV:default} substitution works regardless of timing (Java parity).

pub fn from_reader(reader: &ConfigReader) -> Self

Build a config from a loaded reader. Public so tests and tooling can exercise the enabled/disabled paths deterministically (the Java package-private constructor’s analog).

pub fn is_enabled(&self) -> bool

pub fn render( &self, state: &TraceState, log_time: SystemTime, ) -> Map<String, Value>

Build the context block for one log line (Java render): reserved tokens resolved live, constants, then the developer’s custom keys. Keys resolving to nothing are omitted.

state is the current trace bracket — the context block exists ONLY for a log line emitted inside a traced function execution with a real request trace (Java parity: the log context is registered per worker execution in lockstep with the trace bracket; framework, system and telemetry lines carry no context at all, not even the constants).
