Struct LogConfig 

pub struct LogConfig {
    pub level: LogLevel,
    pub message: Value,
    pub fields: HashMap<String, Value>,
    pub compiled_message: Option<Arc<Logic>>,
    pub compiled_fields: Vec<(String, Option<Arc<Logic>>)>,
}

Configuration for the log function.

The message and field expressions are pre-compiled at startup.

Fields

level: LogLevel

Log level to emit at

message: Value

JSONLogic expression to produce the log message string

fields: HashMap<String, Value>

Additional structured fields: each value is a JSONLogic expression

compiled_message: Option<Arc<Logic>>

Pre-compiled message JSONLogic, populated by LogicCompiler.

compiled_fields: Vec<(String, Option<Arc<Logic>>)>

Pre-compiled JSONLogic for each fields entry, populated by LogicCompiler. The inner Option is None for fields whose logic failed to compile (logged at engine construction).

Implementations

impl LogConfig

pub fn execute( &self, message: &mut Message, engine: &Arc<Engine>, ) -> Result<(TaskOutcome, Vec<Change>)>

Execute the log function, opening a fresh thread-local arena scope.

Use this entry point when calling LogConfig outside an existing with_arena scope (direct API users, tests). Inside a workflow sync stretch the dispatch goes through Self::execute_in_arena to reuse the cached ArenaContext and avoid a redundant to_arena walk.

Trait Implementations

impl Clone for LogConfig

fn clone(&self) -> LogConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LogConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LogConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
