Enum StashResult 

#[non_exhaustive]
pub enum StashResult<M> {
    Stashed {
        depth: usize,
    },
    Rejected(M),
    DroppedOldest(M),
    DroppedNewest,
}

Result of BoundedStash::stash.

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.

Stashed

Stashed successfully; depth is the new buffer length.

Fields

depth: usize

Rejected(M)

Reject policy refused the message; caller must route it (e.g. publish on DeadLetters).

DroppedOldest(M)

DropOldest displaced an existing message; caller may want to surface it on DeadLetters.

DroppedNewest

DropNewest discarded the incoming message — depth unchanged.

Trait Implementations

impl<M: Clone> Clone for StashResult<M>

fn clone(&self) -> StashResult<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug> Debug for StashResult<M>

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

Formats the value using the given formatter.

impl<M: PartialEq> PartialEq for StashResult<M>

fn eq(&self, other: &StashResult<M>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
