Enum DevicePriority

pub enum DevicePriority {
    Low,
    Normal,
    High,
    Critical,
}

Device priority levels for connection management.

The manager never disconnects a device on its own to make room for another: when the connection limit is reached, connect() fails, and DeviceManager::evict_lowest_priority frees a slot when you call it, unless a connect() of the device it picks keeps that device connected. The health monitor (DeviceManager::start_health_monitor) reconnects lost devices highest priority first.

Variants

Low

Low priority: evicted first by evict_lowest_priority.

Normal

Normal priority (default).

High

High priority: evicted only when no Low or Normal device is connected.

Critical

Critical priority: never evicted.

Trait Implementations

impl Clone for DevicePriority

fn clone(&self) -> DevicePriority

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DevicePriority

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

Formats the value using the given formatter.

impl Default for DevicePriority

fn default() -> DevicePriority

Returns the “default value” for a type.

impl Ord for DevicePriority

fn cmp(&self, other: &DevicePriority) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DevicePriority

fn eq(&self, other: &DevicePriority) -> 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 PartialOrd for DevicePriority

fn partial_cmp(&self, other: &DevicePriority) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
