pub unsafe fn adopt_bytes(ptr: *mut u8, len: usize) -> Option<Vec<u8>>Expand description
Adopt a run from alloc (or one this runtime returned) as an owned
vector. Null with a length of 0 is the empty run; null with any other
length yields None.
ยงSafety
ptr must be null or a run of exactly len bytes from alloc or
bytes_into_raw that nothing else releases or uses afterward.
