Structs

• Error
  The Error type, a wrapper around a dynamic error type.
• Executor
  Solves an optimization problem with a solver
• IterState
  Maintains the state from iteration to iteration of a solver
• KV
  A simple key-value storage

  Maintains the state from iteration to iteration of a solver
• OptimizationResult
  Result of an optimization returned by after running an Executor.
• PopulationState
  Maintains the state from iteration to iteration of a population-based solver
• Problem
  Wrapper around problems defined by users.

Enums

• ArgminError
  Argmin error type
• KvValue
  Types available for use in KV.
• TerminationReason
  Reasons for optimization algorithms to stop
• TerminationStatus
  Status of optimization execution

Traits

• ArgminFloat
  An alias for float types (f32, f64) which combines multiple commonly needed traits from num_traits, std::fmt and for serialization/deserialization (the latter only if the serde1 feature is enabled). It is automatically implemented for all types which fulfill the trait bounds.
• CostFunction
  Defines computation of a cost function value
• Gradient
  Defines the computation of the gradient.
• Hessian
  Defines the computation of the Hessian.
• Jacobian
  Defines the computation of the Jacobian.
• LinearProgram
  Defines a linear Program
• Operator
  Defines the application of an operator to a parameter vector.
• SendAlias
  Trait alias for Send
• Solver
  The interface all solvers are required to implement.
• State
  Minimal interface which struct used for managing state in solvers have to implement.
• SyncAlias
  Trait alias for Sync
