Enum Demand 

pub enum Demand {
    Camera,
    Microphone,
    Watch,
    Telephony,
    Bluetooth,
    Nfc,
    Wifi,
    Location,
}

Hardware an application cannot run without.

Every other feature stays optional, so the application reaches devices that lack the hardware and asks the framework at run time.

Variants

Camera

A camera.

Microphone

A microphone.

Watch

A watch.

Telephony

Telephony.

Bluetooth

Bluetooth.

Nfc

Near-field communication.

Wifi

Wi-Fi.

Location

Location hardware.

Implementations

impl Demand

pub const fn android_feature(self) -> &'static str

The Android feature name this demand becomes.

pub const fn name(self) -> &'static str

The name this demand carries in the build’s own files.

Trait Implementations

impl Clone for Demand

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Demand

impl Eq for Demand

impl Ord for Demand

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Demand

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Demand

fn partial_cmp(&self, other: &Self) -> 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.
