Functions

derive_enum_variant_method

Generic helper for EnumIsA and EnumAsGetters. This generates one function per variant.

derive_variant_index_arity

Macro to derive a function fn variant_index_arity(&self) -> (u32, usize) the pair (variant index, variant arity). Only works on enumerations, of course.

derive_variant_name

Macro to derive a function fn variant_name(&self) -> String printing the constructor of an enumeration. Only works on enumerations, of course.

generate_variant_match_patterns 🔒

Generate matching patterns for an enumeration.

to_snake_case 🔒

We initially used the convert-case crate, but it converts names like “I32” to “i_32”, while we want to get “i32”. We thus reimplemented our own converter (which removes one dependency at the same time).
