Implementations

impl Texture

pub fn is_dsa(&self) -> bool

Returns true if the Texture is backed by a DSA backend

pub fn load_data<T: 'static>(
    &mut self,
    data: &[T],
    format: DataFormat
) -> Result<()>

Upload data to the texture

The function will check that the data dimensions are correct for the passed format and the allocated size.

DataFormat implements Default so it usually doesn’t need to be fully specified see it’s documentation for more information.

pub fn load_buffer<T: 'static, B>(
    &mut self,
    buffer: &B,
    format: DataFormat
) -> Result<()> where
    B: BufferRange<T>, 

Load data to the texture from a Buffer

The function will check that the data dimensions are correct for the passed format and the allocated size

DataFormat implements Default so it usually doesn’t need to be fully specified see it’s documentation for more information.

pub fn load_compressed_data<T: 'static>(
    &mut self,
    data: &[T],
    format: CompressedDataFormat
) -> Result<()>

Upload data to the texture

The function will check that the data dimensions are correct for the passed format and the allocated size. Also that the passed texture format is the same as the allocated internal

CompressedDataFormat implements Default so it usually doesn’t need to be fully specified see it’s documentation for more information.
