Struct RedactingVisitor 

pub struct RedactingVisitor {
    pub fields: BTreeMap<String, String>,
}

A tracing field visitor that records (name, redacted value) pairs into a map. Runtimes use it in their formatters; tests use it to prove the redaction rules.

Fields

fields: BTreeMap<String, String>
