Types ¶
type Allocator ¶
type Allocator struct {
// contains filtered or unexported fields
}
func NewAllocator ¶
func NewAllocator() *Allocator
type Closure ¶
type Closure struct {
*Procedure
// contains filtered or unexported fields
}
func (*Closure) CheckArity ¶
CheckArity performs a compile-time arity check for the Closure
type Procedure ¶
type Procedure struct {
ArityChecker data.ArityChecker
isa.Runnable
// contains filtered or unexported fields
}
Procedure encapsulates the initial environment of an abstract machine
func MakeProcedure ¶
func MakeProcedure(run *isa.Runnable, arity data.ArityChecker) *Procedure
func (*Procedure) Call ¶
Call allows an abstract machine Procedure to be called to instantiate a Closure. Only the compiler invokes this calling interface.
func (*Procedure) CheckArity ¶
CheckArity performs a compile-time arity check for the Procedure
