Enum fna3d::SetDataOptions

#[repr(u32)]pub enum SetDataOptions {
    None,
    Discard,
    NoOverwrite,
}

How vertex or index buffer data will be flushed during a SetData operation.

Variants

None

The SetData operation can overwrite the portions of existing data.

Discard

The SetData operation will discard the entire buffer. A pointer to a new memory area is returned and rendering from the previous area do not stall

NoOverwrite

The SetData operation will not overwrite existing data. This allows the driver to return immediately from a SetData operation and continue rendering.
