Enum QueueEmptyBehavior 

pub enum QueueEmptyBehavior {
    Yes,
    No,
    Strict,
    Unknown(String),
}

Whether callers may join, or are kept in, a queue with no available members. Used by both join_when_empty and leave_when_empty.

Variants

Yes

Callers may join / remain with no members.

No

Callers may not join / are sent to failover.

Strict

Like No, but also applies when members are present yet all unavailable.

Unknown(String)

Any wire value this crate doesn’t recognize.

Implementations

impl QueueEmptyBehavior

pub fn as_wire(&self) -> &str

The wire string for this variant.

pub fn from_wire(s: &str) -> Self

Parse a wire string. Unknown values are preserved.

Trait Implementations

impl Clone for QueueEmptyBehavior

fn clone(&self) -> QueueEmptyBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueueEmptyBehavior

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueueEmptyBehavior

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for QueueEmptyBehavior

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

Formats the value using the given formatter.

impl Eq for QueueEmptyBehavior

impl Hash for QueueEmptyBehavior

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QueueEmptyBehavior

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

impl Serialize for QueueEmptyBehavior

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
