Struct RectF

pub struct RectF {
    pub x: f32,
    pub y: f32,
    pub width: f32,
    pub height: f32,
}

A floating point, rectangular, axis-aligned region in a 2D cartesian space.

This type does not specify units. Protocols that use this type should specify the characteristics of the vector space, including orientation and units.

Fields

x: f32

The location of the origin of the rectangle in the x-axis.

y: f32

The location of the origin of the rectangle in the y-axis.

width: f32

The distance along the x-axis.

If width is positive, the region includes x values starting at x and increasing along the x-axis. If width is negative, the region includes x values starting at x and decreasing along the x-axis.

height: f32

The distance along the y-axis.

If height is positive, the region includes y values starting at y and increasing along the y-axis. If height is negative, the region includes y values starting at y and decreasing along the y-axis.

Trait Implementations

impl Clone for RectF

fn clone(&self) -> RectF

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RectF

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

Formats the value using the given formatter.

impl<D> Decode<RectF, D> for RectF

where D: ResourceDialect,

fn new_empty() -> RectF

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl<D> Encode<RectF, D> for &RectF

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for RectF

fn eq(&self, other: &RectF) -> 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 PartialOrd for RectF

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

impl TypeMarker for RectF

type Owned = RectF

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for RectF

type Borrowed<'a> = &'a RectF

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<RectF as TypeMarker>::Owned, ) -> <RectF as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.

impl Copy for RectF

impl Persistable for RectF

impl StructuralPartialEq for RectF
