Question about refer to module method

help
1

Hi there, I've encountered a strange syntax

#[must_use]
#[stable(feature = "rust1", since = "1.0.0")]
#[inline]
pub fn is_control(self) -> bool {
    unicode::Cc(self)
}

the Cc is confusing to me, it refers to module cc's method lookup, but I've got no idea how it works


#[rustfmt::skip]
pub mod cc {
    static SHORT_OFFSET_RUNS: [u32; 1] = [
        1114272,
    ];
    static OFFSETS: [u8; 5] = [
        0, 32, 95, 33, 0,
    ];
    pub fn lookup(c: char) -> bool {
        super::skip_search(
            c as u32,
            &SHORT_OFFSET_RUNS,
            &OFFSETS,
        )
    }
}

it's just re-exported as an alias. see:

Thanks for answering! I thought it’s some kind of syntax sugar that I’m not aware of :person_facepalming:.

Maybe rust-analyzer should have the ability to hint the alias (or maybe its already hinted but got ignored by me
