Module hdk::prelude::allocation

Functions

• __hc__allocate_1
  Allocate bytes that won’t be dropped by the allocator. Return the pointer to the leaked allocation so the host can write to it.
• __hc__deallocate_1
  Free an allocation. Needed because we leak memory every time we call __hc__allocate_1 and write_bytes.
• consume_bytes
  Attempt to consume bytes from a known guest_ptr and len.
• write_bytes
  Given an owned vector of bytes, leaks it and returns a pointer the host can use to read the bytes. This does NOT handle the length of the bytes, so the guest will need to track the length separately from leaking the vector.
