Enum libcamera::controls::AfTrigger

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

This control starts an autofocus scan when AfMode is set to AfModeAuto, and can also be used to terminate a scan early.

It is ignored if AfMode is set to AfModeManual or AfModeContinuous.

Variants

Start = 0

Start an AF scan. 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 = 33u32

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

type Primitive = i32

const NAME: &'static str = "AfTrigger"

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