Enum OverflowStrategy 

pub enum OverflowStrategy {
    Block,
    Drop,
    Expand,
    DropOldest,
    Reject,
}

Strategy for handling overflow when all workers are busy.

This enum defines different strategies for handling situations where all worker threads are occupied and new tasks arrive.

Examples

use subx_cli::config::OverflowStrategy;

let strategy = OverflowStrategy::Block;
assert_eq!(strategy, OverflowStrategy::Block);

// Comparison and serialization
let strategies = vec![
    OverflowStrategy::Block,
    OverflowStrategy::Drop,
    OverflowStrategy::Expand,
];
assert_eq!(strategies.len(), 3);

Variants

Block

Block until a worker becomes available.

This is the safest option as it ensures all tasks are processed, but may cause the application to become unresponsive.

Drop

Drop new tasks when all workers are busy.

Use this when task loss is acceptable and responsiveness is critical.

Expand

Create additional temporary workers.

This can help with load spikes but may consume excessive resources.

DropOldest

Drop oldest tasks in queue.

Prioritizes recent tasks over older ones in the queue.

Reject

Reject new tasks.

Similar to Drop but may provide error feedback to the caller.

Trait Implementations

impl Clone for OverflowStrategy

fn clone(&self) -> OverflowStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverflowStrategy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OverflowStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for OverflowStrategy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
