Struct OutBufferWrapper 

pub(crate) struct OutBufferWrapper<'a, 'b, C: WriteBuf + ?Sized> {
    pub(crate) buf: ZSTD_outBuffer,
    pub(crate) parent: &'a mut OutBuffer<'b, C>,
}

Interface between a C-level ZSTD_outBuffer and a rust-level OutBuffer.

Will update the parent buffer from the C buffer on drop.

Fields

buf: ZSTD_outBuffer

parent: &'a mut OutBuffer<'b, C>

Implementations

impl<'a, 'b, C: WriteBuf + ?Sized> OutBufferWrapper<'a, 'b, C>

pub(crate) fn check(&mut self, res: SafeResult) -> SafeResult

Passes res through, and forgets the position reported by zstd if it is an error, so the parent keeps the one from before the call.

zstd.h makes no promise about pos after a failed call, and the legacy decoders report the whole output buffer as written when they fail; only a successful call vouches for the bytes up to pos being initialized.

Trait Implementations

impl<'a, 'b: 'a, C: WriteBuf + ?Sized> Deref for OutBufferWrapper<'a, 'b, C>

type Target = ZSTD_outBuffer_s

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, 'b: 'a, C: WriteBuf + ?Sized> DerefMut for OutBufferWrapper<'a, 'b, C>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'a, 'b, C: WriteBuf + ?Sized> Drop for OutBufferWrapper<'a, 'b, C>

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.
