Enum AfTrigger

#[repr(i32)]
pub enum AfTrigger {
    Start = 0,
    Cancel = 1,
}

Start an autofocus scan.

This control starts an autofocus scan when AfMode is set to AfModeAuto, and is ignored if AfMode is set to AfModeManual or AfModeContinuous. It can also be used to terminate a scan early.

Variants

Start = 0

Start an AF scan.

Setting the control to AfTriggerStart is ignored if a scan is in progress.

Cancel = 1

Cancel an AF scan.

This does not cause the lens to move anywhere else. Ignored if no scan is in progress.

Trait Implementations

impl Clone for AfTrigger

fn clone(&self) -> AfTrigger

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ControlEntry for AfTrigger

const ID: u32 = 38u32

impl Debug for AfTrigger

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

Formats the value using the given formatter.

impl From<AfTrigger> for ControlValue

fn from(val: AfTrigger) -> Self

Converts to this type from the input type.

impl From<AfTrigger> for i32

fn from(enum_value: AfTrigger) -> Self

Converts to this type from the input type.

impl PartialEq for AfTrigger

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

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 AfTrigger

type Error = TryFromPrimitiveError<AfTrigger>

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 AfTrigger

const NAME: &'static str = "AfTrigger"

type Primitive = i32

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>
