Enum StashOverflow 

#[non_exhaustive]
pub enum StashOverflow {
    DropOldest,
    DropNewest,
    Reject,
}

What to do when the stash is full and a new message arrives.

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.

DropOldest

Drop the oldest stashed message; queue the new one.

DropNewest

Drop the new message.

Reject

Drop the new message AND surface it to the caller as an error (so the runtime can route it to DeadLetters).

Trait Implementations

impl Clone for StashOverflow

fn clone(&self) -> StashOverflow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StashOverflow

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

Formats the value using the given formatter.

impl PartialEq for StashOverflow

fn eq(&self, other: &StashOverflow) -> 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.
