Expand description

A compile-time proof that a memory operation is safe.

ATS2 requires explicit proof terms for memory operations. Each proof corresponds to a specific safety property:

  • AllocProof: the allocation succeeded (non-null for non-nullable types)
  • FreeProof: the pointer is valid and owned, so freeing is safe
  • BorrowProof: the pointer is valid for the duration of the borrow
  • BoundsProof: array index is within the allocated bounds
  • NullCheckProof: a nullable pointer has been checked for NULL

Variants§

§

AllocProof

Proves that an allocation returned a valid (non-null) pointer.

Fields

§viewtype: String

The viewtype of the allocated resource.

§

FreeProof

Proves that a pointer is valid and owned, permitting deallocation.

Fields

§ptr_id: String

The linear pointer being freed.

§

BorrowProof

Proves that a borrowed pointer remains valid for the borrow’s scope.

Fields

§ptr_id: String

The linear pointer being borrowed.

§mutable: bool

Whether the borrow is read-only or read-write.

§

BoundsProof

Proves that an index is within the bounds of a sized buffer.

Fields

§buffer_id: String

The buffer being indexed.

§index_expr: String

The index expression.

§

NullCheckProof

Proves that a nullable pointer has been checked for NULL.

Fields

§ptr_id: String

The nullable pointer that was checked.
