A submodule containing composers for elements indexed by some totally ordered domain type.

val required : 'k -> 'r model -> ('v -> 'r) -> ('k index, 'v) bind

Use required k v f to compose a group field where a required output value with key k and value matching the model v obtained by applying the projector f to the rendered value.

val optional : 'k -> 'r model -> ('v -> 'r option) -> ('k index, 'v) bind

Use optional k v f to compose a group field where an optional output value with key k and value matching the model v obtained by applying the projector f to the rendered value. If the projector returns None then no field with key k is output.

val constant : 'k -> 'r model -> 'r -> ('k index, 'v) bind

Use constant k v def to compose a group field where a required output value with key k and value def matching the model v is produced regardless of the rendered value.
