Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Op

pub unsafe fn from_sqe_unchecked(sqe: &Sqe) -> Option<Op>

Decode the raw SQE into an Op with borrowed buffers passed as slices.

Safety

Any borrowed buffers will be unmapped whenever a response is sent, which unlike the move-based CallRequest API, needs to be managed manually by the caller.

Trait Implementations

impl Debug for Op

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

Formats the value using the given formatter.

impl IntoTag for Op

fn into_tag(self) -> Tag
