It is currently not possible to tell if a function or method is a const fn by reading documentation, as rustdoc does not retain the const keyword in const fn declarations #76478

Description

@slightlyoutofphase

Basically, a function written for example like this:

pub const fn add(a: i32, b: i32) -> i32 {
    a + b
}

is currently documented like this:

pub fn add(a: i32, b: i32) -> i32

but it would be nice if was instead documented like this:

pub const fn add(a: i32, b: i32) -> i32
