Struct FieldMeta 

pub struct FieldMeta {
    pub name: &'static str,
    pub number: u32,
    pub role: FieldRole,
    pub cardinality: Cardinality,
    pub classification: Classification,
}

Compile-time field metadata emitted by codegen alongside each EventSchema impl. Mirrors the proto-side obs.v1.FieldMeta.

Fields

name: &'static str

number: u32

Proto field number.

role: FieldRole

Codegen-classified role.

cardinality: Cardinality

LABEL cardinality cap; Unspecified for non-labels.

classification: Classification

Classification (drives redaction / SECRET strip).
