# Objective Fixes #6931 Continues #6954 by squashing `Msaa` to a flat enum Helps out #7215 # Solution ``` pub enum Msaa { Off = 1, #[default] Sample4 = 4, } ``` # Changelog - Modified - `Msaa` is now enum - Defaults to 4 samples - Uses `.samples()` method to get the sample number as `u32` # Migration Guide ``` let multi = Msaa { samples: 4 } // is now let multi = Msaa::Sample4 multi.samples // is now multi.samples() ``` Co-authored-by: Sjael <jakeobrien44@gmail.com>

//! This example shows how to configure Multi-Sample Anti-Aliasing. Setting the sample count higher
|
|
//! will result in smoother edges, but it will also increase the cost to render those edges. The
|
|
//! range should generally be somewhere between 1 (no multi sampling, but cheap) to 8 (crisp but
|
|
//! expensive).
|
|
//! Note that WGPU currently only supports 1 or 4 samples.
|
|
//! Ultimately we plan on supporting whatever is natively supported on a given device.
|
|
//! Check out [this issue](https://github.com/gfx-rs/wgpu/issues/1832) for more info.
