Struct Priority 

pub struct Priority {
    pub level: i32,
    pub fairness_key: String,
    pub fairness_weight: u32,
}

Where a step waiting for a permit stands. The default (level 0, no key, weight 1) is plain arrival order.

Fields

level: i32

Higher levels are served first. A lower level waits while any higher one has waiters.

fairness_key: String

Waiters at one level are grouped by this key (a tenant ID, say) and the groups take turns. Empty: the shared group of unkeyed waiters.

fairness_weight: u32

Permits the key takes in each turn; 0 counts as 1. The latest waiter of a key sets its weight.

Implementations

impl Priority

pub fn is_default(&self) -> bool

Trait Implementations

impl Clone for Priority

fn clone(&self) -> Priority

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Priority

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

Formats the value using the given formatter.

impl Default for Priority

fn default() -> Priority

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Priority

where Priority: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Priority

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 Priority

fn eq(&self, other: &Priority) -> 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 Priority

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Priority
