In fact, only the `derivative_uniformity` triggering rule exists in the WGSL standard. That said, Naga contributors are excited to see how this level of control unlocks a new ecosystem of configurable diagnostics. - Finally, `diagnostic(…)` rules are not yet emitted in WGSL output. This means that `wgsl-in` → `wgsl-out` is currently a lossy process. We felt that it was important to unblock users who needed `diagnostic(…)` rules (i.e., ) before we took significant effort to fix this (tracked in ). -By @ErichDonGubler in [#6456](https://github.com/gfx-rs/wgpu/pull/6456), [#6148](https://github.com/gfx-rs/wgpu/pull/6148), [#6533](https://github.com/gfx-rs/wgpu/pull/6533), [#6353](https://github.com/gfx-rs/wgpu/pull/6353). +By @ErichDonGubler in [#6456](https://github.com/gfx-rs/wgpu/pull/6456), [#6148](https://github.com/gfx-rs/wgpu/pull/6148), [#6533](https://github.com/gfx-rs/wgpu/pull/6533), [#6353](https://github.com/gfx-rs/wgpu/pull/6353), [#6537](https://github.com/gfx-rs/wgpu/pull/6537). ### New Features @@ -3482,4 +3482,4 @@ DeviceDescriptor { - concept of the storage hub - basic recording of passes and command buffers - submission-based lifetime tracking and command buffer recycling -- automatic resource transitions \ No newline at end of file +- automatic resource transitions diff --git a/naga/src/diagnostic_filter.rs b/naga/src/diagnostic_filter.rs index 48fe44af3..2fa5464cd 100644 --- a/naga/src/diagnostic_filter.rs +++ b/naga/src/diagnostic_filter.rs @@ -59,22 +59,35 @@ impl Severity { #[cfg_attr(feature = "deserialize", derive(Deserialize))] #[cfg_attr(feature = "arbitrary", derive(Arbitrary))] pub enum FilterableTriggeringRule { + Standard(StandardFilterableTriggeringRule), + Unknown(Box), + User(Box<[Box; 2]>), +} + +/// A filterable triggering rule in a [`DiagnosticFilter`]. +/// +/// +#[derive(Clone, Copy, Debug, Eq, Hash, Ord, PartialEq, PartialOrd)] +#[cfg_attr(feature = "serialize", derive(Serialize))] +#[cfg_attr(feature = "deserialize", derive(Deserialize))] +#[cfg_attr(feature = "arbitrary", derive(Arbitrary))] +pub enum StandardFilterableTriggeringRule { DerivativeUniformity, } -impl FilterableTriggeringRule { +impl StandardFilterableTriggeringRule { /// The default severity associated with this triggering rule. /// /// See for a table of default /// severities. pub(crate) const fn default_severity(self) -> Severity { match self { - FilterableTriggeringRule::DerivativeUniformity => Severity::Error, + Self::DerivativeUniformity => Severity::Error, } } } -/// A filter that modifies how diagnostics are emitted for shaders. +/// A filtering rule that modifies how diagnostics are emitted for shaders. /// /// #[derive(Clone, Debug)] @@ -230,13 +243,13 @@ pub struct DiagnosticFilterNode { impl DiagnosticFilterNode { /// Finds the most specific filter rule applicable to `triggering_rule` from the chain of /// diagnostic filter rules in `arena`, starting with `node`, and returns its severity.
