Struct Shader 

pub struct Shader {
    pub definition: ShaderDefinition,
    pub cache_index: Arc<AtomicIndex>,
}

Internal state of the shader.

Notes

Usually you don’t need to access internals of the shader, but there sometimes could be a need to read shader definition, to get supported passes and properties.

Fields

definition: ShaderDefinition

Shader definition contains description of properties and render passes.

cache_index: Arc<AtomicIndex>

An id that can be used to create associated GPU resources.

Implementations

impl Shader

pub const DEFINITION: &'static str = "definition"

impl Shader

pub async fn from_file<P>( path: P, io: &(dyn ResourceIo + 'static), ) -> Result<Shader, ShaderError>

where P: AsRef<Path>,

Creates a shader from file.

pub fn from_string(str: &str) -> Result<Shader, ShaderError>

Creates a shader from string.

pub fn from_string_bytes(bytes: &[u8]) -> Result<Shader, ShaderError>

Creates a shader from string represented as raw bytes. This function will fail if the bytes does not contain Utf8-encoded string.

pub fn find_texture_resource( &self, name: &str, ) -> Option<&ShaderResourceDefinition>

Tries to find a texture resource with the specified name.

pub fn find_property_group_resource( &self, name: &str, ) -> Option<&ShaderResourceDefinition>

Tries to find a property group resource with the specified name.

pub fn has_texture_resource(&self, name: &str) -> bool

Checks if this shader has a texture resource with the specified name.

pub fn has_property_group_resource(&self, name: &str) -> bool

Checks if this shader has a property group resource with the specified name.

Trait Implementations

impl Clone for Shader

fn clone(&self) -> Shader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shader

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

Formats the value using the given formatter.

impl Default for Shader

fn default() -> Shader

Returns the “default value” for a type.

impl Reflect for Shader

where Shader: 'static,

fn source_path() -> &'static str

fn try_clone_box(&self) -> Option<Box<dyn Reflect>>

fn type_name(&self) -> &'static str

fn derived_types() -> &'static [TypeId]

fn query_derived_types(&self) -> &'static [TypeId]

fn doc(&self) -> &'static str

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

impl ResourceData for Shader

fn type_uuid(&self) -> Uuid

Returns unique data type id.

fn save(&mut self, path: &Path) -> Result<(), Box<dyn Error>>

Saves the resource data a file at the specified path. This method is free to decide how the resource data is saved. This is needed, because there are multiple formats that defines various kinds of resources. For example, a rectangular texture could be saved into a bunch of formats, such as png, bmp, tga, jpg etc., but in the engine it is single Texture resource. In any case, produced file should be compatible with a respective resource loader.

fn can_be_saved(&self) -> bool

Returns true if the resource data can be saved to a file, false - otherwise. Not every resource type supports saving, for example there might be temporary resource type that is used only at runtime which does not need saving at all.

fn try_clone_box(&self) -> Option<Box<dyn ResourceData>>

Tries to clone the resource data. This method can return None if the underlying type is non-cloneable.

impl TypeUuidProvider for Shader

fn type_uuid() -> Uuid

Return type UUID.

impl Visit for Shader

fn visit(&mut self, name: &str, visitor: &mut Visitor) -> Result<(), VisitError>

Read or write this value, depending on whether Visitor::is_reading() is true or false.
