Rustdoc: No link to source for trait provided methods

[aDotInTheVoid]

I tried this code:

pub trait Numbers {
    fn get_a_number(&self) -> i32;

    fn get_larger_number(&self) -> i32 {
        self.get_a_number() + 1
    }
}

pub struct NumberFive;

impl Numbers for NumberFive {
    fn get_a_number(&self) -> i32 {
        5
    }
}

I expected to see this happen: Provided method Numbers::get_larger_number has link to source

Instead, it doesnt.

Interestingly on the docs for impl Numbers for NumberFive include the link, even though the impl is in the trait definition, not the block implementing the trait for Numbers.
