When compiling unit tests in the pre-cq, the Cargo.lock file is deleted.
Testing a sub-crate without a lock file will cause the protobuf

Previously, the getter and setter functions generated for a bitfield
struct by #[bitfield] all operated on primitive types like bool, u8, u16
etc.
This CL adds support for getters and setters defined in terms of
user-defined enums.
We make an enum bitfield-compatible by adding #[bitfield]. The number of
variants must be a power of 2.
#[bitfield]
enum TwoBits {
Zero = 0b00,
One = 0b01,
Two = 0b10,
Three = 0b11,
}
And then it may be used to specify a field in a bitfield struct.
#[bitfield]
struct Struct {
prefix: BitField1,
two_bits: TwoBits,
suffix: BitField5,
}
The generated getters and setters for this struct would have the
following signatures:
impl Struct {
fn get_prefix(&self) -> u8;
fn set_prefix(&mut self, val: u8);
fn get_two_bits(&self) -> TwoBits;
fn set_two_bits(&mut self, val: TwoBits);
fn get_suffix(&self) -> u8;
fn set_suffix(&mut self, val: u8);
}
