Module glast::diag

All diagnostic types.

Diagnostics are split across two main types:

• Syntax for all syntax/grammar-related diagnostics,
• Semantic for all semantics-related diagnostics.

All diagnostic types are marked #[non_exhaustive] to allow for new diagnostics to be introduced without a breaking change. All diagnostic types have a get_severity() method which returns the Severity of that given diagnostic. Syntax diagnostics only return Severity::Error.

There are a lot of individual syntax diagnostics for all sorts of edge cases. This approach was chosen in order to provide very specific and precise diagnostics without having to hardcode &'static strings everywhere. In order to make the amount more managable, most diagnostics are split into nested enums.

Enums

PreprocLineDiag

Syntax diagnostics for the #line directive.

PreprocVersionDiag

Syntax diagnostics for the #version directive.

Semantic

All semantic diagnostics.

Severity

The severity of a diagnostic.

StmtDiag

Syntax
