Struct RequestedFormat 

pub struct RequestedFormat<'a> { /* private fields */ }

A request to the camera for a valid CameraFormat

Implementations

impl RequestedFormat<'_>

pub fn new<Decoder>(requested: RequestedFormatType) -> RequestedFormat<'static>

where Decoder: FormatDecoder,

Creates a new RequestedFormat by using the RequestedFormatType and getting the FrameFormat constraints from a generic type.

pub fn with_formats( requested: RequestedFormatType, decoder: &[FrameFormat], ) -> RequestedFormat<'_>

Creates a new RequestedFormat by using the RequestedFormatType and getting the FrameFormat constraints from a statically allocated slice.

pub fn requested_format_type(&self) -> RequestedFormatType

Gets the RequestedFormatType

pub fn fulfill(&self, all_formats: &[CameraFormat]) -> Option<CameraFormat>

Fulfill the requested using a list of all available formats.

See RequestedFormatType for more details.

Trait Implementations

impl<'a> Clone for RequestedFormat<'a>

fn clone(&self) -> RequestedFormat<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RequestedFormat<'a>

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

Formats the value using the given formatter.

impl Display for RequestedFormat<'_>

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

Formats the value using the given formatter.

impl<'a> Hash for RequestedFormat<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for RequestedFormat<'a>

fn cmp(&self, other: &RequestedFormat<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for RequestedFormat<'a>

fn eq(&self, other: &RequestedFormat<'a>) -> 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<'a> PartialOrd for RequestedFormat<'a>

fn partial_cmp(&self, other: &RequestedFormat<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
