Module hdk::prelude::allocation

Functions

__allocate	Allocate a length plus a length prefix in bytes that won’t be dropped by the allocator. Return the pointer to it so a length prefix + bytes can be written to the allocation.
__deallocate	Free a length-prefixed allocation. Needed because we leak memory every time we call __allocate and write_bytes.
consume_bytes	Attempt to consume bytes out of a length-prefixed allocation at the given pointer position.
length_prefix_at_guest_ptr	Attempt to extract the length at the given guest_ptr.
write_bytes	Attempt to write a slice of bytes into a length prefixed allocation.
