Struct CoreLog 

pub struct CoreLog {
    pub target: String,
    pub message: String,
    pub timestamp: SystemTime,
    pub level: Level,
    pub fields: HashMap<String, Value>,
    pub span_contexts: Vec<String>,
}

A log line (which ultimately came from a tracing event) exported from Core->Lang

Fields

target: String

The module within core this message originated from

message: String

Log message

timestamp: SystemTime

Time log was generated (not when it was exported to lang)

level: Level

Message level

fields: HashMap<String, Value>

Arbitrary k/v pairs (span k/vs are collapsed with event k/vs here). We could change this to include them in span_contexts instead, but there’s probably not much value for log forwarding.

span_contexts: Vec<String>

A list of the outermost to the innermost span names
