Builder struct and methods do not have generated documentation

[JohnstonJ]

This is not generating all documentation with version 1.3.2 from crates.io:

/// Some struct
#[bitbybit::bitfield(u32)]
pub struct BbyBTest {
    /// lspi
    #[bits(11..=31, rw)]
    pub lspi: u21,

    /// sec ext
    #[bit(10, rw)]
    pub security_extn: bool,

    /// cpu num
    #[bits(7..=9, rw)]
    pub cpu_number: u3,

    /// lin num
    #[bits(0..=6, rw)]
    pub itlines_number: u7,
}

These warnings only come up when the builder is generated. I generated the documentation, and indeed, the builder struct + all the methods on it are missing documentation.

Thanks for the report! I'll look into it
