Crate calyx_frontend

Frontend parsing and AST representation.

Defines the frontend AST and the parser. The frontend representation is transformed into the representation defined in the ir module.

Re-exports

pub use ast::NamespaceDef;

Modules

ast

Abstract Syntax Tree for Calyx

parser

Parser for Calyx programs.

Structs

Attributes

Attributes associated with a specific IR structure.

LibrarySignatures

A representation of all the primitive definitions found while parsing the root program.

PortDef

Definition of a port parameterized by a width type. Ports on Primitives can be parameteris and use Width. Ports on Components cannot be parameterized and therefore use u64.

Primitive

Representation of a external primitive definition.

Workspace

A Workspace represents all Calyx files transitively discovered while trying to compile a top-level file.

Enums

Attribute

Defines the known attributes that can be attached to IR nodes. All caps names represent attributes that are internal to the compiler and cannot be parsed back.

BoolAttr

Attributes that are only allowed to take boolean values.

Direction

Direction of a port on a cell.

InternalAttr

Internal attributes that cannot be parsed back from the IL.

NumAttr

Attributes that can take numeric values

PrimitiveInfo

Tracks the information for Primitives defined in the program.

Width

Represents an abstract width of a primitive signature.

Constants

DEPRECATED_ATTRIBUTES

Attributes that have been deprecated.

Traits

GetAttributes

Structs that can return an Attributes instance.
