Struct ShaderArgsBuilder

pub struct ShaderArgsBuilder { /* private fields */ }

An object to build the uniforms data for a GLShader.

GLib type: Shared boxed type with reference counted clone semantics.

Implementations

impl ShaderArgsBuilder

pub fn as_ptr(&self) -> *mut GskShaderArgsBuilder

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GskShaderArgsBuilder) -> &Self

Borrows the underlying C value.

impl ShaderArgsBuilder

pub fn new( shader: &GLShader, initial_values: Option<&Bytes>, ) -> ShaderArgsBuilder

👎Deprecated: Since 4.16

Allocates a builder that can be used to construct a new uniform data chunk.

Deprecated since 4.16

GTK’s new Vulkan-focused rendering does not support this feature. Use GtkGLArea for OpenGL rendering.

value

value to set the uniform to

pub fn set_uint(&self, idx: i32, value: u32)

👎Deprecated: Since 4.16

Sets the value of the uniform @idx.

The uniform must be of uint type.

Deprecated since 4.16

pub fn set_vec2(&self, idx: i32, value: &Vec2)

Sets the value of the uniform @idx.

The uniform must be of vec2 type.

Deprecated since 4.16

👎Deprecated: Since 4.16

Sets the value of the uniform @idx.

The uniform must be of vec4 type.

Deprecated since 4.16

pub fn to_args(self) -> Bytes

👎Deprecated: Since 4.16

Creates a new GBytes args from the current state of the given @self.

Any uniforms of the shader that have not been explicitly set on the @self are zero-initialized.

The given ShaderArgsBuilder is reset once this function returns; you cannot call this function multiple times on the same @self instance.

This function is intended primarily for bindings. C code should use Gsk::ShaderArgsBuilder::free_to_args().

Deprecated since 4.16

GTK’s new Vulkan-focused rendering does not support this feature. Use GtkGLArea for OpenGL rendering.

Returns

the newly allocated buffer with all the args added to @self

Trait Implementations

impl Clone for ShaderArgsBuilder

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the reference. Dropping the reference will decrement it again.

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

Performs copy-assignment from source.

impl Debug for ShaderArgsBuilder

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

Formats the value using the given formatter.

impl From<ShaderArgsBuilder> for Value

fn from(s: ShaderArgsBuilder) -> Self

Converts to this type from the input type.

impl HasParamSpec for ShaderArgsBuilder

type ParamSpec = ParamSpecBoxed

type SetValue = ShaderArgsBuilder

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, ShaderArgsBuilder>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ShaderArgsBuilder

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 ShaderArgsBuilder

fn cmp(&self, other: &ShaderArgsBuilder) -> 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 ShaderArgsBuilder

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

fn partial_cmp(&self, other: &ShaderArgsBuilder) -> 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 StaticType for ShaderArgsBuilder

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for ShaderArgsBuilder
