Struct MeshRouting 

pub struct MeshRouting {
    pub links: Vec<Vec<Link>>,
    pub occupancy: Vec<Vec<(Link, u8)>>,
    pub legal: bool,
    pub router: &'static str,
}

The vector nets of one placement, routed. For every net, in order: the mesh links it occupies, and its occupancy keys — (link, 0) for a channel of a directed link, ((cell, cell), 1) for a perimeter port carrying DRAM → mesh and ((cell, cell), 2) for mesh → DRAM — so that the largest count over keys of a legal routing never exceeds the channel budget.

Fields

links: Vec<Vec<Link>>

occupancy: Vec<Vec<(Link, u8)>>

legal: bool

Every net connected and no resource shared, by a check independent of the router.

router: &'static str

Which router (and rung) produced the routes, as a Placement reports it.
