Struct EnqueueOptions 

#[non_exhaustive]
pub struct EnqueueOptions<'a> {
    pub ordering_key: Option<&'a str>,
}

Options specific to one enqueue call (contract §4 #9): the application-supplied ordering_key, which is deliberately not part of Metadata (§22.2).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

ordering_key: Option<&'a str>

The ordering-strategy key this message belongs to. None (the default) means unordered.

Implementations

impl<'a> EnqueueOptions<'a>

pub const fn ordering_key(self, key: &'a str) -> Self

Sets Self::ordering_key. #[non_exhaustive] forbids struct-literal construction outside this crate, so this is the only way to set a non-default value.

Trait Implementations

impl<'a> Clone for EnqueueOptions<'a>

fn clone(&self) -> EnqueueOptions<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for EnqueueOptions<'a>

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

Formats the value using the given formatter.

impl<'a> Default for EnqueueOptions<'a>

fn default() -> EnqueueOptions<'a>

Returns the “default value” for a type.
