Enum ProblemHint 

pub enum ProblemHint {
    None,
    Linear,
    Quadratic,
}

Hint about problem structure for closure-based objectives.

When the objective is provided as a closure (ObjectiveKind::Minimize), the auto-selector cannot determine if the underlying function is linear or quadratic. Setting a hint informs solver selection without requiring coefficient extraction.

Variants

None

No structural information (default).

Linear

The closure implements a linear function.

Quadratic

The closure implements a quadratic function.

Trait Implementations

impl Clone for ProblemHint

fn clone(&self) -> ProblemHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProblemHint

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

Formats the value using the given formatter.

impl Default for ProblemHint

fn default() -> ProblemHint

Returns the “default value” for a type.

impl PartialEq for ProblemHint

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

Tests for self and other values to be equal, and is used by ==.

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

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