Enum HdrChannel

#[repr(i32)]
pub enum HdrChannel {
    None = 0,
    Short = 1,
    Medium = 2,
    Long = 3,
}

The HDR channel used to capture the frame.

This value is reported back to the application so that it can discover whether this capture corresponds to the short or long exposure image (or any other image used by the HDR procedure). An application can monitor the HDR channel to discover when the differently exposed images have arrived.

This metadata is only available when an HDR mode has been enabled.

\sa HdrMode

Variants

None = 0

This image does not correspond to any of the captures used to create an HDR image.

Short = 1

This is a short exposure image.

Medium = 2

This is a medium exposure image.

Long = 3

This is a long exposure image.

Trait Implementations

impl Clone for HdrChannel

fn clone(&self) -> HdrChannel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ControlEntry for HdrChannel

const ID: u32 = 44u32

impl Debug for HdrChannel

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

Formats the value using the given formatter.

impl From<HdrChannel> for ControlValue

fn from(val: HdrChannel) -> Self

Converts to this type from the input type.

impl From<HdrChannel> for i32

fn from(enum_value: HdrChannel) -> Self

Converts to this type from the input type.

impl PartialEq for HdrChannel

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

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 HdrChannel

type Error = TryFromPrimitiveError<HdrChannel>

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 HdrChannel

const NAME: &'static str = "HdrChannel"

type Primitive = i32

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