Enum let_engine::resources::data::Data

pub enum Data {
    Fixed {
        vertices: &'static [Vertex],
        indices: &'static [u32],
    },
    Dynamic {
        vertices: Vec<Vertex>,

    },
}

Vertex and index data for the appearance and shape of objects. Has 3 simple presets.

Empty, Square and Triangle.

Right now it only supports 2d model data.

The models must have vertices and indices.

up is -y, down is +y. right is +x und left is -x.

Variants

Fixed

Fields

vertices: &'static [Vertex]

indices: &'static [u32]

Never changing model data

Dynamic

Fields

vertices: Vec<Vertex>

indices: Vec<u32>

Model data that may change

Implementations

impl Data

pub const fn new_dynamic(vertices: Vec<Vertex>, indices: Vec<u32>) -> Self

Creates new dynamically resizable modeldata with the given vertices and indices.

pub const fn new_fixed( vertices: &'static [Vertex], indices: &'static [u32] ) -> Self

Creates new fixed sized modeldata with the given vertices and indices.

pub fn square() -> Self

Returns the data of a square that goes from -1.0 to 1.0 in both X and Y.

pub fn triangle() -> Self

Returns the data of a triangle with the points [0.0, -1.0], [-1.0, 1.0], [1.0, 1.0].

pub fn is_empty(&self) -> bool

Returns if the data has an empty field.

pub fn vertices(&self) -> &[Vertex]

Returns a slice of bytes of the vertices of this data.

pub fn indices(&self) -> &[u32]

Returns a slice of bytes of the indices of this data.

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.

impl PartialEq for Data

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