Function issues_rows 

pub fn issues_rows(
    layout: &Layout,
    project_filter: Option<&str>,
    state_filter: Option<&str>,
    ready_only: bool,
) -> Result<Vec<IssueRow>>

The same rows, still typed.

A caller that has to publish the shape it returns needs the type rather than the value: a schema taken from IssueRow cannot disagree with what this hands back, and one written beside it can.

Errors

Returns an error if the corpus cannot be read or the filter is not a state.
