Derive Macro proc_bitfield::ConvRaw

#[derive(ConvRaw)]

A derive macro to implement any applicable conversion traits between an enum and the builtin integer and boolean types corresponding to variant discriminants.

Usage example

(Generated type docs)

/// An enum showcasing the `ConvRaw` derive for converting from/into integers.
#[derive(ConvRaw)]
pub enum ConvRawIntExample {
    A,
    B = 2,
    C,
    D = -1,
    E = 1,
    F = -128,
    G = 128,
}

This will implement:

• TryFrom<T> for ConvRawIntExample for all integer types T
• UnsafeFrom<T> for ConvRawIntExample for all integer types T
• From<ConvRawIntExample> for T for all integer types T that contain all discriminants; in this case, all signed integer types with >= 16 bits (i16, i32, i64, i128)
• From<bool> for ConvRawBoolExample
• From<ConvRawBoolExample> for bool

/// An enum showcasing the `ConvRaw` derive for converting from/into booleans.
#[derive(ConvRaw)]
pub enum ConvRawBoolExample {
    False, // Implicitly, this value is treated as 0 (false).
    True,
}

This will implement:

• TryFrom<T> for ConvRawBool for all integer types T
• UnsafeFrom<T> for ConvRawBool for all integer types T
• From<ConvRawBool> for T for all integer types T that contain all discriminants; in this case, all integer types
• From<bool> for ConvRawBoolExample
• From<ConvRawBoolExample> for bool
