Enum AeronIdleStrategyKind 

pub enum AeronIdleStrategyKind {
    Sleeping,
    Yielding,
    BusySpin,
    NoOp,
    Backoff,
}

Aeron’s named idle strategies, as accepted by the context / media-driver set_*_idle_strategy options (the C aeron_idle_strategy_load symbol table).

Strategy parameters are configured separately via set_idle_strategy_init_args:

• Sleeping: sleep period in nanoseconds (e.g. "1000000" = 1ms)
• Backoff: maxSpins-maxYields-minParkNs-maxParkNs (e.g. "10-20-1000-1000000")
• Others: init args ignored

Variants

Sleeping

Sleep when idle ("sleeping"); period from the init args.

Yielding

Yield the OS thread when idle ("yield").

BusySpin

Busy-spin ("spin") — lowest latency, pins a core.

NoOp

Never back off ("noop").

Backoff

Spin, then yield, then park with exponential backoff ("backoff") — the default.

Implementations

impl AeronIdleStrategyKind

pub const fn name(&self) -> &'static str

The name the C loader expects.

pub const fn name_c(&self) -> &'static CStr

Self::name as a compile-time C string — lets setters pass it straight to the FFI with no runtime allocation.

impl AeronIdleStrategyKind

pub const fn default_init_args(&self) -> &'static str

Default init args accepted by this strategy’s loader (the C client validates the currently-set init args when the strategy is set, so they must be coherent): sleeping takes a period in ns; backoff takes maxSpins-maxYields-minParkNs-maxParkNs (hyphen-separated); the rest ignore init args.

pub const fn default_init_args_c(&self) -> &'static CStr

Self::default_init_args as a compile-time C string (no runtime allocation).

Trait Implementations

impl Clone for AeronIdleStrategyKind

fn clone(&self) -> AeronIdleStrategyKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AeronIdleStrategyKind

impl Debug for AeronIdleStrategyKind

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

Formats the value using the given formatter.

impl Eq for AeronIdleStrategyKind

impl PartialEq for AeronIdleStrategyKind

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