Enum ExposureMetering

    CenterWeighted = 1,
    Spot = 2,
    Matrix = 3,
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Average = 0

CenterWeighted = 1

Spot = 2

Matrix = 3

Trait Implementations

impl AsRef<u32> for ExposureMetering

fn as_ref(&self) -> &u32

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ExposureMetering

fn clone(&self) -> ExposureMetering

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExposureMetering

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

Formats the value using the given formatter.

impl Deref for ExposureMetering

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for ExposureMetering

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

Formats the value using the given formatter.

impl From<ExposureMetering> for u32

fn from(data: ExposureMetering) -> Self

Converts to this type from the input type.

impl PartialEq for ExposureMetering

fn eq(&self, other: &ExposureMetering) -> 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<u32> for ExposureMetering

type Error = u32

The type returned in the event of a conversion error.

fn try_from(data: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ExposureMetering

impl Eq for ExposureMetering

impl StructuralPartialEq for ExposureMetering
