Struct HeaderFieldSpec

    pub rust_field: &'static str,
    pub key: &'static str,
    pub aliases: &'static [&'static str],
    pub alias_conflict: AliasConflictPolicy,

}

Static schema metadata for one non-flattened header field.

Fields

rust_field: &'static str

Rust source field name.

key: &'static str

Canonical wire key used by encoders.

aliases: &'static [&'static str]

Ordered decode-only aliases.

alias_conflict: AliasConflictPolicy

Canonical/alias conflict behavior.

kind: HeaderValueKind

Protocol value category.

presence: HeaderPresence

Missing-field behavior.

default_semantic: Option<&'static str>

Stable literal or dynamic default semantic identifier.

java_type: Option<&'static str>

Optional Java type override for compatibility tooling.

Tooling should infer the normal wire category from Self::kind when this is None. Production headers only set this for exceptional mappings that cannot be inferred from the Rust value type.

java_range: Option<HeaderRange>

Signed Java range imposed on an unsigned Rust value.

binary_order: u16

Stable field order within the declaring header.

declared_in: &'static str

Stable type identifier of the declaring header.
