Struct ndk::native_window::NativeWindowTransform

pub struct NativeWindowTransform(/* private fields */);

Transforms that can be applied to buffers as they are displayed to a window.

Supported transforms are any combination of horizontal mirror, vertical mirror, and clockwise 90 degree rotation, in that order. Rotations of 180 and 270 degrees are made up of those basic transforms.

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_retain(bits: i32) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

pub const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl NativeWindowTransform

pub const fn iter(&self) -> Iter<NativeWindowTransform>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<NativeWindowTransform>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
