Enum OverflowPolicy 

pub enum OverflowPolicy {
    Err,
    DiscardOldest,
}

Controls what happens when enqueue is called on a full RAM ring.

Variants

Err

Return Err(()) — the caller decides whether to drop the item or drain first.

DiscardOldest

Silently discard the oldest buffered item(s) to make room for the new one.

The new item is always accepted as long as it physically fits in the ring (i.e. data.len() + 2 <= RAM_BYTES).

Trait Implementations

impl Clone for OverflowPolicy

fn clone(&self) -> OverflowPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverflowPolicy

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

Formats the value using the given formatter.

impl PartialEq for OverflowPolicy

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