Module spans

Utilities for dealing with span tracking in the compiler and in error reporting.

Macros

expr_to_span 🔒

Generates a ToSpan implementation for a type implementing rowan::AstNode. This is impossible to do as a blanket implementation because rustc forbids these implementations for traits from third-party crates due to a belief that semantic versioning truly could work (it doesn’t).

Structs

EntireFile

A placeholder ToSpan implementation covering the entire source file.

OrEntireFile

A placeholder ToSpan implementation which falls back to the entire file if its wrapped value is None

Traits

ToSpan

Trait implemented by all types from which we can retrieve a span.
