Struct RawVarZeroCow 

struct RawVarZeroCow {
    buf: NonNull<[u8]>,
    owned: bool,
}

VarZeroCow without the V to simulate a dropck eyepatch (i.e., prove to rustc that the dtor is not able to observe V or ’a)

This is effectively Cow<'a, [u8]>, with the lifetime managed externally

Fields

buf: NonNull<[u8]>

Pointer to data

Safety Invariants

1. This slice must always be valid as a byte slice
2. If owned is true, this slice can be freed.
3. VarZeroCow, the only user of this type, will impose an additional invariant that the buffer is a valid V

owned: bool

The buffer is Box<[u8]> if true

Implementations

impl RawVarZeroCow

pub fn is_owned(&self) -> bool

Whether or not this is owned

pub fn as_bytes(&self) -> &[u8]

Get the byte representation of this type

Trait Implementations

impl Clone for RawVarZeroCow

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for RawVarZeroCow

Available on crate feature alloc only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
