Enum libcamera::controls::AfMetering

#[repr(i32)]
pub enum AfMetering {
    Auto = 0,
    Windows = 1,
}

Instruct the AF algorithm how it should decide which parts of the image should be used to measure focus.

Variants

Auto = 0

The AF algorithm should decide for itself where it will measure focus.

Windows = 1

The AF algorithm should use the rectangles defined by the AfWindows control to measure focus. If no windows are specified the behaviour is platform dependent.

Trait Implementations

impl Clone for AfMetering

fn clone(&self) -> AfMetering

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ControlEntry for AfMetering

const ID: u32 = 31u32

impl Debug for AfMetering

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

Formats the value using the given formatter.

impl From<AfMetering> for ControlValue

fn from(val: AfMetering) -> Self

Converts to this type from the input type.

impl From<AfMetering> for i32

fn from(enum_value: AfMetering) -> Self

Converts to this type from the input type.

impl PartialEq for AfMetering

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

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 AfMetering

type Error = TryFromPrimitiveError<AfMetering>

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 AfMetering

type Primitive = i32

const NAME: &'static str = "AfMetering"

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

impl Control for AfMetering
