Futhark.Manifest
Contents
Description
C manifest data structure and serialisation to JSON.
A manifest contains machine-readable information about the API of the compiled Futhark program. Specifically which entry points are available, which types are exposed, and what their C names are. This module documentation is not intended as a full description of the Futhark C API - you will need to consult the Futhark User's Guide to understand most of the information here.
The type aliases are purely informative and do not actually enforce correct usage. They are present only because most of the information here is ultimately just text.

Type aliases
The name of a Futhark-level type. This may be an array type
(without sizes, just empty brackets), a primitive type, or another
string denoting an opaque type. The latter must have a
corresponding entry in manifestTypes.
Manifest
A manifest for a compiled program.

Manifest info for a non-scalar type. Scalar types are not part of the manifest for a program. Although this representation allows a type to be both a a record and a sum type, this will never actually happen.
Constructors
| TypeArray CTypeName TypeName Int ArrayOps | ctype, Futhark elemtype, rank. |
| TypeOpaque CTypeName OpaqueOps (Maybe RecordOps) (Maybe SumOps) |
The names of the C functions implementing the operations on some array type.

data RecordField Source #
Information about a record field.
Constructors
| RecordField | |
Fields
| |
Instances
Some opaque types are records, from which we can extract fields, and also construct them from values for their fields. Beyond that, they support the usual opaque operations. These record facilities can be ignored if you wish, and the types treated as ordinary opaque types.

data SumVariant Source #
Information about a variant of a sum type.
Constructors
| SumVariant | |
Fields
| |
Instances
Some opaque types are sum types, from which we can (try to) extract the payload of a constructor, as well as construct them from payloads. As with records, we can ignore these facilities and simply treat them as completely opaque.
