Struct grb::Constr

pub struct Constr { /* private fields */ }

A linear constraint added to a Model

To interact with the attributes of a constraint, use Model::get_obj_attr and Model::set_obj_attr

Trait Implementations

impl Clone for Constr

fn clone(&self) -> Constr

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Constr

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

Formats the value using the given formatter.

impl Hash for Constr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl ModelObject for Constr

fn id(&self) -> u32

Retrieve the object’s ID.

impl ObjAttrGet<Constr, ConstrSense> for ConstrSenseAttr

fn get(&self, model: &Model, idx: i32) -> Result<ConstrSense>

Get the value for this attribute

fn get_batch<I: IntoIterator<Item = Result<i32>>>( &self, model: &Model, inds: I ) -> Result<Vec<ConstrSense>>

Get multiple values for this attribute at once

impl ObjAttrSet<Constr, ConstrSense> for ConstrSenseAttr

fn set(&self, model: &Model, idx: i32, val: ConstrSense) -> Result<()>

Set the value for this attribute

fn set_batch<I: IntoIterator<Item = (Result<i32>, ConstrSense)>>( &self, model: &Model, idx_val_pairs: I ) -> Result<()>

Set multiple values for this attribute at once

impl ObjAttrSet<Constr, i8> for ConstrSenseAttr

fn set(&self, model: &Model, idx: i32, val: c_char) -> Result<()>

Set the value for this attribute

fn set_batch<I: IntoIterator<Item = (Result<i32>, c_char)>>( &self, model: &Model, idx_val_pairs: I ) -> Result<()>

Set multiple values for this attribute at once

impl PartialEq for Constr

fn eq(&self, other: &Constr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
