Enum libcamera::controls::AePrecaptureTrigger

#[repr(i32)]
pub enum AePrecaptureTrigger {
    Idle = 0,
    Start = 1,
    Cancel = 2,
}

Control for AE metering trigger. Currently identical to ANDROID_CONTROL_AE_PRECAPTURE_TRIGGER.

Whether the camera device will trigger a precapture metering sequence when it processes this request.

Variants

Idle = 0

The trigger is idle.

Start = 1

The pre-capture AE metering is started by the camera.

Cancel = 2

The camera will cancel any active or completed metering sequence. The AE algorithm is reset to its initial state.

Trait Implementations

impl Clone for AePrecaptureTrigger

fn clone(&self) -> AePrecaptureTrigger

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ControlEntry for AePrecaptureTrigger

const ID: u32 = 38u32

impl Debug for AePrecaptureTrigger

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

Formats the value using the given formatter.

impl From<AePrecaptureTrigger> for ControlValue

fn from(val: AePrecaptureTrigger) -> Self

Converts to this type from the input type.

impl From<AePrecaptureTrigger> for i32

fn from(enum_value: AePrecaptureTrigger) -> Self

Converts to this type from the input type.

impl PartialEq for AePrecaptureTrigger

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

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 AePrecaptureTrigger

type Error = TryFromPrimitiveError<AePrecaptureTrigger>

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 AePrecaptureTrigger

type Primitive = i32

const NAME: &'static str = "AePrecaptureTrigger"

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