Struct fidl_fuchsia_ui_gfx::SetMaterialCmd

#[repr(C)]
pub struct SetMaterialCmd {
    pub node_id: u32,
    pub material_id: u32,
}

Sets/clears a node’s material.

Constraints:

• node_id refs a Node with the has_material characteristic.
• material_id refs a Material, or nothing.
• if this command causes the target to have both a Shape and a Material, then these must be compatible with each other (see README.md regarding “Shape/Material Compatibility”).

Discussion: In order to be painted, a node requires both a Shape and a Material. Without a material, a node can still participate in hit-testing and clipping. Without a shape, a node cannot do any of the above.

Fields

node_id: u32

material_id: u32

Trait Implementations

impl Clone for SetMaterialCmd

fn clone(&self) -> SetMaterialCmd

Returns a copy of the value.

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

impl Debug for SetMaterialCmd

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

Formats the value using the given formatter.

impl Decode<SetMaterialCmd> for SetMaterialCmd

fn new_empty() -> Self

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<'_>, offset: usize, _depth: Depth ) -> Result<()>

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

impl Encode<SetMaterialCmd> for &SetMaterialCmd

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

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

impl<T0: Encode<u32>, T1: Encode<u32>> Encode<SetMaterialCmd> for (T0, T1)

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

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

impl FromBytes for SetMaterialCmdwhere u32: FromBytes,

fn read_from<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from bytes.

fn read_from_prefix<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from the prefix of bytes.

fn read_from_suffix<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from the suffix of bytes.

fn new_zeroed() -> Selfwhere Self: Sized,

Creates an instance of Self from zeroed bytes.

impl Hash for SetMaterialCmd

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

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 Ord for SetMaterialCmd

fn cmp(&self, other: &SetMaterialCmd) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SetMaterialCmd> for SetMaterialCmd

fn eq(&self, other: &SetMaterialCmd) -> 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.

impl PartialOrd<SetMaterialCmd> for SetMaterialCmd

fn partial_cmp(&self, other: &SetMaterialCmd) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TypeMarker for SetMaterialCmd

type Owned = SetMaterialCmd

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 SetMaterialCmd

type Borrowed<'a> = &'a <SetMaterialCmd as TypeMarker>::Owned

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<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

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