Crate ecore_macro 

ecore-macro

Procedural macros for the ecore crate.

Macros

Macro	Description
#[derive(MapEnum)]	Generate enum-to-array mapping with optional discriminant enum
#[bitfld(...)]	Attribute macro for defining bitfield structs and enums
map_enum!	Const-friendly enum variant → value mapping
rint!	Compile-time ranged integer type generator
#[derive(BitsCast)]	Derive bit-level casting between representations
#[derive(IterEnumDiscriminants)]	Derive iteration over enum discriminants

Usage

Add to Cargo.toml:

[dependencies]
ecore = "0.10"
ecore-macro = "0.10"

Nightly: const trait impls

Enable the const-trait feature to generate const fn trait implementations (requires nightly Rust with #![feature(const_trait_impl)]):

ecore-macro = { version = "0.10", features = ["const-trait"] }

MSRV

Rust 1.87+

Macros

map_enum

Map enum to EnumMap, macro version for EnumMap::map_new, can move value, can invoke in const, requires import EnumMap and MapEnum

rint

Generate RInt type from value range, auto select RRxx value type

Attribute Macros

bitfld

Define bit field struct or bit field enum or bit field

Derive Macros

BitsCast

Derive BitsCast (for enum only right now)

IterEnumDiscriminants

Derive IterEnumDiscriminants for enum, providing compile-time iteration over all discriminant names and their associated integer values.

MapEnum

Derive MapEnum for enum
