Enum AfPauseState

#[repr(i32)]
pub enum AfPauseState {
    Running = 0,
    Pausing = 1,
    Paused = 2,
}

Report whether the autofocus is currently running, paused or pausing.

This control is only applicable in continuous (AfModeContinuous) mode, and reports whether the algorithm is currently running, paused or pausing (that is, will pause as soon as any in-progress scan completes).

Any change to AfMode will cause AfPauseStateRunning to be reported.

Variants

Running = 0

Continuous AF is running and the algorithm may restart a scan spontaneously.

Pausing = 1

Continuous AF has been sent an AfPauseDeferred control, and will pause as soon as any in-progress scan completes.

When the scan completes, the AfPauseState control will report AfPauseStatePaused. No new scans will be start spontaneously until the AfPauseResume control is sent.

Paused = 2

Continuous AF is paused.

No further state changes or lens movements will occur until the AfPauseResume control is sent.

Trait Implementations

impl Clone for AfPauseState

fn clone(&self) -> AfPauseState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ControlEntry for AfPauseState

const ID: u32 = 42u32

impl Debug for AfPauseState

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

Formats the value using the given formatter.

impl From<AfPauseState> for ControlValue

fn from(val: AfPauseState) -> Self

Converts to this type from the input type.

impl From<AfPauseState> for i32

fn from(enum_value: AfPauseState) -> Self

Converts to this type from the input type.

impl PartialEq for AfPauseState

fn eq(&self, other: &AfPauseState) -> 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 TryFrom<ControlValue> for AfPauseState

type Error = ControlValueError

The type returned in the event of a conversion error.

fn try_from(value: ControlValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<i32> for AfPauseState

type Error = TryFromPrimitiveError<AfPauseState>

The type returned in the event of a conversion error.

fn try_from(number: i32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for AfPauseState

const NAME: &'static str = "AfPauseState"

type Primitive = i32
