sourcepub fn bit_depth(&self) -> u16
pub fn bit_depth(&self) -> u16
Returns the bit depth of this video mode, as in how many bits you have available per color. This is generally 24 bits or 32 bits on modern systems, depending on whether the alpha channel is counted or not.
§Platform-specific
- Wayland / Orbital: Always returns 32.
- iOS: Always returns 32.
