Memory

The Memory namespace is used to allocate schematics with enumerable and non-enumerable properties as well as track of allocations made by the type system.

Metrics

The Memory namespace includes a Metrics property that tracks allocations created within the type system. You can use this property to inspect memory usage, debug, or gain insights into the allocations required during instantiation.

const Reverse = Type.Script(`<T, Result extends unknown[] = []> = (
  T extends [infer L, ...infer R] 
    ? Reverse<R, [L, ...Result]>
    : Result
)`)

const Result = Type.Script({ Reverse }, `Reverse<[
  1, 2, 3, 4, 5, 6, 7, 8
]>`)                                          // TTuple<[
                                              //   TLiteral<8>,
                                              //   TLiteral<7>,
                                              //   ...
                                              //   TLiteral<0>
