Struct ndk::configuration::Configuration

pub struct Configuration { /* private fields */ }

A native AConfiguration *

Configuration is an opaque type used to get and set various subsystem configurations.

Implementations

impl Configuration

pub unsafe fn from_ptr(ptr: NonNull<AConfiguration>) -> Self

Construct a Configuration from a pointer.

Safety

By calling this function, you assert that it is a valid pointer to a native AConfiguration, and give ownership of it to the Configuration instance.

pub unsafe fn clone_from_ptr(ptr: NonNull<AConfiguration>) -> Self

Create a new Configuration, with the same contents as the AConfiguration referenced by the pointer.

This is useful if you have a pointer, but not ownership of it.

Safety

By calling this function, you assert that it is a valid pointer to a native AConfiguration.

pub fn ptr(&self) -> NonNull<AConfiguration>

The pointer to the native AConfiguration. Keep in mind that the Configuration object still has ownership, and will free it when dropped.

pub fn from_asset_manager(am: &AssetManager) -> Self

pub fn new() -> Self

Create a new Configuration, with none of the values set.

pub fn copy(&mut self, other: &Self)

dest.copy(&src) copies the contents of src to dest

pub fn diff(&self, other: &Self) -> DiffResult

Information about what fields differ between the two configurations

pub fn matches(&self, requested: &Self) -> bool

Returns false if anything in self conflicts with requested

pub fn country(&self) -> Option<String>

Returns the country code, as a String of two characters, if set

pub fn density(&self) -> Option<u32>

Returns the screen density in dpi.

On some devices it can return values outside of the density enum.

pub fn keyboard(&self) -> Keyboard

Returns the keyboard type.

pub fn keys_hidden(&self) -> KeysHidden

Returns keyboard visibility/availability.

pub fn language(&self) -> Option<String>

Returns the language, as a String of two characters, if set

pub fn layout_direction(&self) -> LayoutDir

Returns the layout direction

pub fn mcc(&self) -> i32

Returns the mobile country code.

pub fn mnc(&self) -> Option<i32>

Returns the mobile network code, if one is defined

pub fn nav_hidden(&self) -> NavHidden

pub fn navigation(&self) -> Navigation

pub fn orientation(&self) -> Orientation

pub fn screen_height_dp(&self) -> Option<i32>

pub fn screen_width_dp(&self) -> Option<i32>

pub fn screen_long(&self) -> ScreenLong

pub fn screen_round(&self) -> ScreenRound

Available on crate feature api-level-30 only.

pub fn screen_size(&self) -> ScreenSize

pub fn sdk_version(&self) -> i32

pub fn smallest_screen_width_dp(&self) -> Option<i32>

pub fn touchscreen(&self) -> Touchscreen

pub fn ui_mode_night(&self) -> UiModeNight

pub fn ui_mode_type(&self) -> UiModeType

Trait Implementations

impl Clone for Configuration

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Configuration

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

Formats the value using the given formatter.

impl Drop for Configuration

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for Configuration

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
