Struct Solved 

pub struct Solved { /* private fields */ }

A solved trellis: a Trellis paired with the minimum-cost Path through it.

Solved is a certificate, not a cache — the only way to construct one is Trellis::solve, and the trellis inside is immutable, so holding a Solved guarantees its path describes its trellis. Leaving is consuming: append to grow it, reopen to mutate it.

Implementations

impl Solved

pub fn path(&self) -> &Path

The minimum-cost path through the trellis.

pub fn cost(&self) -> u32

The path’s total cost.

pub fn trellis(&self) -> &Trellis

The solved trellis, read-only.

pub fn append( self, width: u32, ) -> Result<(Trellis, LayerId), (Solved, TrellisError)>

Grow by one layer, returning to the building state with the new layer’s id. The path is discarded — it no longer spans every layer. A rejected width hands the certificate back untouched.

pub fn reopen(self) -> Trellis

Return to the building state for surgery or windowing, discarding the path.
