Struct MioInstaller 

pub struct MioInstaller<S = Box<dyn Handler<Event>>> { /* private fields */ }

Mio driver installer — generic over handler storage.

S is the handler storage type. Defaults to Box<dyn Handler<mio::event::Event>>.

Consumed by WorldBuilder::install_driver. Registers a MioDriver<S> resource and returns a MioPoller for poll-time use.

Examples

// Defaults: 1024 events, 64 handlers
let poller = builder.install_driver(MioInstaller::new());

// Custom capacities
let poller = builder.install_driver(
    MioInstaller::new()
        .event_capacity(256)
        .handler_capacity(32),
);

Implementations

impl<S> MioInstaller<S>

pub fn new() -> Self

Creates a new mio installer with default capacities.

Defaults:

• event_capacity: 1024 (mio events buffer)
• handler_capacity: 64 (slab pre-allocation)

pub fn event_capacity(self, cap: usize) -> Self

Set the mio events buffer capacity (default: 1024).

This is the maximum number of readiness events returned per poll() call. Events beyond this limit are deferred to the next poll.

pub fn handler_capacity(self, cap: usize) -> Self

Set the initial handler slab pre-allocation (default: 64).

The slab grows automatically if more handlers are inserted. Pre-allocating avoids reallocation during early setup.

Trait Implementations

impl<S> Default for MioInstaller<S>

fn default() -> Self

Returns the “default value” for a type.

impl<S: Send + 'static> Installer for MioInstaller<S>

type Poller = MioPoller<S>

The concrete poller returned after installation.

fn install(self, world: &mut WorldBuilder) -> MioPoller<S>

Register resources into the world and return a poller for dispatch.
