Enum libcamera::controls::AePrecaptureTrigger

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

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

The trigger is idle.

Start

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

Cancel

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<AePrecaptureTrigger> for AePrecaptureTrigger

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method 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 = _

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