Enum libcamera::controls::AfSpeed

#[repr(i32)]
pub enum AfSpeed {
    Normal = 0,
    Fast = 1,
}

Control that determines whether the AF algorithm is to move the lens as quickly as possible or more steadily. For example, during video recording it may be desirable not to move the lens too abruptly, but when in a preview mode (waiting for a still capture) it may be helpful to move the lens as quickly as is reasonably possible.

Variants

Normal = 0

Move the lens at its usual speed.

Fast = 1

Move the lens more quickly.

Trait Implementations

impl Clone for AfSpeed

fn clone(&self) -> AfSpeed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ControlEntry for AfSpeed

const ID: u32 = 30u32

impl Debug for AfSpeed

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

Formats the value using the given formatter.

impl From<AfSpeed> for ControlValue

fn from(val: AfSpeed) -> Self

Converts to this type from the input type.

impl From<AfSpeed> for i32

fn from(enum_value: AfSpeed) -> Self

Converts to this type from the input type.

impl PartialEq for AfSpeed

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

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 AfSpeed

type Error = TryFromPrimitiveError<AfSpeed>

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 AfSpeed

type Primitive = i32

const NAME: &'static str = "AfSpeed"

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