# Objective Implements #9216 ## Solution - Replace `DiagnosticId` by `DiagnosticPath`. It's pre-hashed using `const-fnv1a-hash` crate, so it's possible to create path in const contexts. --- ## Changelog - Replaced `DiagnosticId` by `DiagnosticPath` - Set default history length to 120 measurements (2 seconds on 60 fps). I've noticed hardcoded constant 20 everywhere and decided to change it to `DEFAULT_MAX_HISTORY_LENGTH` , which is set to new diagnostics by default. To override it, use `with_max_history_length`. ## Migration Guide ```diff - const UNIQUE_DIAG_ID: DiagnosticId = DiagnosticId::from_u128(42); + const UNIQUE_DIAG_PATH: DiagnosticPath = DiagnosticPath::const_new("foo/bar"); - Diagnostic::new(UNIQUE_DIAG_ID, "example", 10) + Diagnostic::new(UNIQUE_DIAG_PATH).with_max_history_length(10) - diagnostics.add_measurement(UNIQUE_DIAG_ID, || 42); + diagnostics.add_measurement(&UNIQUE_DIAG_ID, || 42); ``` |

Stress tests
These examples are used to stress test Bevy's performance in various ways. These should be run with the "stress-test" profile to accurately represent performance in production, otherwise they will run in cargo's default "dev" profile which is very slow.
Example Command
cargo run --profile stress-test --example <EXAMPLE>
