Attribute Macro bitfield 

#[bitfield]

Creates a bitfield for this struct.

The arguments first, have to begin with the integer type of the bitfield: For example: #[bitfield(u64)].

It can contain the following additional parameters, like the debug argument for disabling the Debug trait generation (#[bitfield(u64, debug = false)]).

Parameters of the bitfield attribute:

• the bitfield integer type (required)
• repr specifies the bitfield’s representation in memory
• from to specify a conversion function from repr to the bitfield’s integer type
• into to specify a conversion function from the bitfield’s integer type to repr
• new to disable the new function generation
• binread to enable the BinRead trait generation
• binwrite to enable the BinWrite trait generation
• binrw to enable both BinRead and BinWrite trait generation
• clone to disable the Clone trait generation
• debug to disable the Debug trait generation
• defmt to enable the defmt::Format trait generation
• default to disable the Default trait generation
• hash to generate the Hash trait
• order to specify the bit order (Lsb, Msb)
• conversion to disable the generation of into_bits and from_bits

For new, clone, debug, defmt or default, you can either use booleans (#[bitfield(u8, debug = false)]) or cfg attributes (#[bitfield(u8, debug = cfg(test))]) to enable/disable them.

Parameters of the bits attribute (for fields):

• the number of bits
• access to specify the access mode (RW, RO, WO, None)
• default to set a default value
• into to specify a conversion function from the field type to the bitfield type
• from to specify a conversion function from the bitfield type to the field type
