Crate enumeration

Provides extension to rust enum

This crate provides crate::enumerate macro to generate rust enum with the following features

• implementation for common traits (Clone, Copy, Hash, etc.)
• implementation of the useful trait enumeration::Enumeration
• getting number of variants through constant enumeration::Enumeration::VARIANT_COUNT
• casting to and from enumeration variant and enumeration index of type enumeration::Enumeration::Index
• associating a constant value with each of the variants (with default value support enumeration::DefaultAssociatedValue)
• iterating through all variants enumeration::Enumeration::iter
• two-way mapping for the variants and the associated constants enumeration::FromValue
• bit-masking support
  • wrapper that redefines some operators for greater bit-masking related bit operations
• limited dynamic dispatch feature
  • allow different [enumeration::Enumeration<Index = T>] to cast into variant::Variant<T>

Modules

• bitmask
  This module provide helper traits and macro for bit related enumeration
• enumeration
  This module provides the core trait Enumeration
• helper
  This modules provides utilities to the crate
• prelude
  Convenience re-export of common members
• variant
  This module provides runtime representation of enumeration

Macros

• bit_enum
  A specialized version of crate::enumerate, it requires a non-optional associated value type (currently only integers are supported) that are automatically defined for each variant
• count
• enumerate
  This macro helps to create enum with trait Enumeration.
• impl_default
• impl_from_value
• impl_try_from_into
• validate
