Enum InvocationMode 

pub enum InvocationMode {
    OnNewData,
    Always,
}

Per-callback invocation mode.

Controls whether a callback fires only when new data is available or on every spin iteration that passes the trigger gate.

Variants

OnNewData

Fire only when has_data() returns true (default).

Always

Fire on every spin iteration, regardless of data availability.

Trait Implementations

impl Clone for InvocationMode

fn clone(&self) -> InvocationMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvocationMode

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

Formats the value using the given formatter.

impl Default for InvocationMode

fn default() -> InvocationMode

Returns the “default value” for a type.

impl PartialEq for InvocationMode

fn eq(&self, other: &InvocationMode) -> 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 Copy for InvocationMode

impl Eq for InvocationMode
