[−][src]Module wlambda::vval

This module provides the core data structures used by the parser, compiler and evaluator of WLambda.

Structs

CompileError
DropVVal	Handles calling of destructor functions.
Env	The runtime environment of the evaluator.
FileRef
LoopInfo
Stdio
SynPos	Structure for holding information about origin of an AST node.
VValFun	This structure is the runtime representation of a WLambda function value.

FunType
StackAction	Encodes all kinds of jumps up the call stack, like `break` and `next` in Loops.
Syntax	Encodes the different types of AST nodes.
UnwindAction	Describes an action that needs to be done when returning from a function or somehow jumps unpredictably around the VM prog.
VVal	VVal aka. VariantValue is a data structure to represent all kinds of WLambda data structures.
VarPos	Position of a variable represented in the `CompileEnv`.

You can implement your own VVal data type and provide it via global functions:
