pub struct Texture { /* fields omitted */ }

Implementations

impl Texture

pub fn generate() -> Texture

Generates a texture.

pub fn create(target: TextureBindTarget) -> Result<Texture, GLError>

Generates a texture with the given target.

Returns GLError::InvalidValue if there’s no current context.

pub fn bind(&self, target: TextureBindTarget) -> GLError

Binds a texture to a texturing target.

When a texture is bound to a target, the previous binding for that target is automatically broken.

Returns GLError::NoError if no error has accured.

Returns GLError::InvalidValue if there’s no current context.

Returns GLError::InvalidOperation if texture was previously created with a target that doesn’t match that of target.

pub fn unbind(target: TextureBindTarget) -> GLError

Binds the zero-named texture to a texturing target.

When a texture is bound to a target, the previous binding for that target is automatically broken.

Returns GLError::NoError if no error has accured.

Returns GLError::InvalidValue if there’s no current context.

pub fn id(&self) -> u32

impl Texture

pub fn set_base_level(target: TextureParameterTarget, level: i32)

Specifies the index of the lowest defined mipmap level.

The initial value is 0.

pub fn set_compare_function(
    &self,
    target: TextureParameterTarget,
    function: TextureCompareFunction
)

Specifies the comparison operator.

The comparison operator is used when TEXTURE_COMPARE_MODE is set to COMPARE_REF_TO_TEXTURE.

pub fn set_compare_mode(
    &self,
    target: TextureParameterTarget,
    mode: TextureCompareMode
)

Specifies the texture comparison mode for currently bound depth textures (the iternal format = DEPTH_COMPONENT).

pub fn set_mag_filter(target: TextureParameterTarget, filter: TextureMagFilter)

Specifies the texture magnification function.

The texture magnification function is used whenever the level-of-detail function used when sampling from the texture determines that the texture should be magified.

Initially, it is set to TextureMagFilter::Linear.

pub fn set_min_filter(target: TextureParameterTarget, filter: TextureMinFilter)

Specifies the texture minifying function.

The texture minifying function is used whenever the level-of-detail function used when sampling from the texture determines that the texture should be minified.

Initially, it is set to TextureMinFilter::LinearMipmapLinear.

pub fn set_wrap_s(target: TextureParameterTarget, value: TextureWrap)

Sets the wrap parameter for texture coordinate s.

Initially, it is set to TextureWrap::Repeat.

pub fn set_wrap_t(target: TextureParameterTarget, value: TextureWrap)

Sets the wrap parameter for texture coordinate t.

Initially, it is set to TextureWrap::Repeat.

pub fn set_wrap_r(target: TextureParameterTarget, value: TextureWrap)

Sets the wrap parameter for texture coordinate r.

Initially, it is set to TextureWrap::Repeat.

impl Texture

pub fn rewrite_image_2d(
    target: Texture2DRewriteTarget,
    mipmap_level: i32,
    texture_internal_format: Texture2DInternalFormat,
    size: [i32; 2],
    image_data_format: ImageDataFormat,
    data: &[u8]
) -> GLError

pub fn write_image_2d(
    target: Texture2DWriteTarget,
    mipmap_level: i32,
    [x, y, width, height]: [i32; 4],
    image_data_format: ImageDataFormat,
    data: &[u8]
) -> GLError

Trait Implementations

impl Drop for Texture

fn drop(&mut self)

Executes the destructor for this type.
