Enum MeshIndexFormat

#[repr(u32)]
pub enum MeshIndexFormat {
    KUint16 = 1,
    KUint32 = 2,
}

Set a mesh’s indices and vertices.

mesh_id refs the Mesh to be updated. index_buffer_id refs a Buffer that contains the mesh indices. index_format defines how the index buffer data is to be interpreted. index_offset number of bytes from the start of the index Buffer. index_count number of indices. vertex_buffer_id refs a Buffer that contains the mesh vertices. vertex_format defines how the vertex buffer data is to be interpreted. vertex_offset number of bytes from the start of the vertex Buffer. vertex_count number of vertices. bounding_box must contain all vertices within the specified range.

The MeshVertexFormat defines which per-vertex attributes are provided by the mesh, and the size of each attribute (and therefore the size of each vertex). The attributes are ordered within the vertex in the same order that they appear within the MeshVertexFormat struct. For example, if the values are kVector3, kNone and kVector2, then:

• each vertex has a position and UV-coordinates, but no surface normal.
• the 3D position occupies bytes 0-11 (3 dimensions * 4 bytes per float32).
• the UV coords occupy bytes 12-19, since no surface normal is provided.

Trait Implementations

impl Clone for MeshIndexFormat

fn clone(&self) -> MeshIndexFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MeshIndexFormat

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<MeshIndexFormat, D> for MeshIndexFormat

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

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

impl<D: ResourceDialect> Encode<MeshIndexFormat, D> for MeshIndexFormat

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 Hash for MeshIndexFormat

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 MeshIndexFormat

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

impl PartialEq for MeshIndexFormat

fn eq(&self, other: &MeshIndexFormat) -> 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 MeshIndexFormat

fn partial_cmp(&self, other: &MeshIndexFormat) -> 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 MeshIndexFormat

type Owned = MeshIndexFormat

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 MeshIndexFormat

type Borrowed<'a> = MeshIndexFormat

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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