Struct KeyShape 

pub struct KeyShape {
    pub prefix: &'static str,
    pub kind: KeyShapeKind,
    pub sub_keys: &'static [KeyEntry],
}

Pattern matcher for indexed / keyed collections under an axis.

software.model.<i>.<sub> is described by a single KeyShape with prefix = "model.", kind = KeyShapeKind::IndexedCollection, and sub_keys = &[("id", String), ("family", String), ...].

software.runtime.<name> is prefix = "runtime.", kind = KeyShapeKind::KeyedMap { value_type: String }, no sub_keys.

Fields

prefix: &'static str

Axis-relative prefix, e.g. model. or runtime.. The trailing . is mandatory.

kind: KeyShapeKind

Pattern kind.

sub_keys: &'static [KeyEntry]

For IndexedCollection patterns, the per-element sub-keys. Empty for KeyedMap patterns.
