Struct BitField 

pub struct BitField {
    pub width: u32,
    pub bit_offset: u64,
    pub signed: bool,
    pub storage: String,
    pub storage_offset: u64,
    pub getter: String,
    pub setter: String,
}

What makes a member a bit-field (C99 6.7.2.1).

A bit-field has no address of its own, so it is not a Rust field: a maximal run of them shares one [u8; K] storage field, and reading or writing one goes through a pair of generated accessors. Everything code generation needs to emit those — where the bits are and how wide they are — lives here.

Fields

width: u32

The declared width, in bits.

bit_offset: u64

The bit offset from the start of the record, counting from the least significant bit of byte 0 (the little-endian bit order every ABI this crate targets uses).

signed: bool

Whether reading the field sign-extends.

Usually the signedness of the declared type; an enum bit-field follows the enumeration’s underlying type instead, which GCC and Clang make unsigned when no enumerator is negative.

storage: String

The name of the [u8; K] field the bits live in.

storage_offset: u64

The byte offset of that field within the record.

getter: String

The name of the generated getter.

setter: String

The name of the generated setter.

Implementations

impl BitField

pub fn offset_in_storage(&self) -> u64
