Crate eset

A simple library for flags like enums.

Unlike crates like enumset or bitflags, this crate relies entirely on rust’s type system to function, with no derive macros required.

This crate does not provide derive functionalities but instead rely on the user to implement the ReprEnum trait. The user can choose to use crates like num_enum and strum to provide additional functionalities.

Macros

• derive_eset
  An opt-in derive that adds Into<ESet<T>> for T and operator BitOr<T, Output=ESet<T>>.
• eset
  Create an ESet with the | syntax.

Structs

• ESet
  An enum set for a fieldless enum T.
• ESetIter
  Enum iterator for ESet

Traits

• ReprEnum
  A trait indicating a type is a enum and can be made into an enum set.
