Trait TextUpload 

pub trait TextUpload {
    // Required method
    fn upload_text(
        &self,
        size: RenderSize,
        rgba8: &[u8],
    ) -> Result<TextPixels, RenderError>;
}

Where TextTextures keeps the pixels of a rasterized text: the GPU renderer uploads them to a texture, the CPU renderer keeps them.

Required Methods

fn upload_text( &self, size: RenderSize, rgba8: &[u8], ) -> Result<TextPixels, RenderError>

Takes rgba8, premultiplied sRGB-encoded RGBA of size with rows packed, as the renderer’s source for that text.

Errors

Returns RenderError::InvalidImageData when rgba8 does not hold size, or the GPU’s upload failure.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
