Struct IndexMapping 

pub struct IndexMapping {
    pub index: IndexName,
    pub hash: ContentHash,
    pub fields: Vec<ResolvedField>,
}

A fully-resolved mapping for one index: every field typed and ready for a sink to translate into its native mapping format.

A source produces this from the IndexSchema — using each field’s explicit Mapping where one is given, and the database’s own column types where it is not. The result has a concrete type for every field, which is what a sink needs to create the index up front rather than leaving the destination to guess.

Fields

index: IndexName

The logical index name (the config key) — the pipeline’s stable identity.

hash: ContentHash

Hash of the parsed index schema. A sink that owns a physical index folds this into the index’s name (e.g. users_3f2a1b9c), so a structural schema change yields a new name — a fresh index that is re-seeded rather than written into the old shape.

fields: Vec<ResolvedField>
