pub fn keyed_assignment_slice<D, K, P, S, const N: usize>(
assignment: &KeyedRosterAssignment<D, K, P, S, N>,
row: impl FnMut(usize, &K, &D, &S, &P) -> Result<Vec<GeneratedToken>, Overflow>,
) -> Result<Vec<GeneratedToken>, Overflow>Expand description
Projects one exact keyed assignment into a borrowed Rust slice expression in denominator order.
The caller supplies every row’s tokens and remains responsible for any item name, visibility, element type, payload meaning, and semantic body surrounding the expression.
§Errors
Returns the first Overflow produced by the row projection or by the completed bracket group.
