Enum PreparedJpeg 

pub enum PreparedJpeg<'a> {
    Borrowed(&'a [u8]),
    Owned(Vec<u8>),
}

Prepared JPEG bytes, borrowed when unchanged and owned when normalized.

Variants

Borrowed(&'a [u8])

Original tile bytes can be decoded directly.

Owned(Vec<u8>)

Preparation changed the byte stream.

Implementations

impl PreparedJpeg<'_>

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

Return decode-ready JPEG bytes.

pub fn try_clone(&self) -> Result<Self, JpegError>

Fallibly duplicate this prepared JPEG.

Borrowed inputs remain borrowed without allocation. Owned normalized payloads are copied through the same typed, capped allocation contract used by dimension rewrite and TIFF assembly.

Errors

Returns JpegError::MemoryCapExceeded when the owned payload exceeds the JPEG host cap, or JpegError::HostAllocationFailed when a cap-valid copy cannot be reserved.

Trait Implementations

impl AsRef<[u8]> for PreparedJpeg<'_>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Debug for PreparedJpeg<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
