Struct IndexedVarBuilder 

pub struct IndexedVarBuilder<'a, K = IndexKey> { /* private fields */ }

Implementations

impl<'a, K> IndexedVarBuilder<'a, K>

pub fn lb(self, v: f64) -> Self

pub fn ub(self, v: f64) -> Self

pub fn bounds(self, lb: f64, ub: f64) -> Self

pub fn lb_by<F>(self, f: F) -> Self

where K: FromIndexKey, F: Fn(K) -> f64 + 'a,

Per-key lower bound. Overrides Self::lb when both are set.

The closure receives a typed index value via FromIndexKey. Annotate the argument to select the projection:

.lb_by(|(p, q): (String, String)| floor_for(&p, &q))
.lb_by(|i: usize| lower_bounds[i])

pub fn ub_by<F>(self, f: F) -> Self

where K: FromIndexKey, F: Fn(K) -> f64 + 'a,

Per-key upper bound. Overrides Self::ub when both are set.

The closure receives a typed index value via FromIndexKey; annotate the argument to select the projection:

.ub_by(|(p, q): (String, String)| capacity_for(&p, &q))
.ub_by(|i: usize| upper_bounds[i])

pub fn domain(self, d: Domain) -> Self

pub fn integer(self) -> Self

pub fn binary(self) -> Self

pub fn build(self) -> IndexedVar<'a, K>

Register one scalar variable per key and return the IndexedVar handle.

Panics

Panics if a scalar variable name collides with one already registered.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
