fn store_mismatch(name: &str, rgba: &[u8], width: u32, height: u32)Available on crate feature
snapshot and non-WebAssembly only.Expand description
Keep a frame that did not match, so a failing run leaves it behind.
Natively, where a test owns its own filesystem: the snapshot’s name is a path relative to the snapshot directory, so it keeps each frame under the test it belongs to rather than colliding on a file name.
