Implementations

impl LineSearch

pub fn backtrack<X, J>( &self, function: impl Fn(&X) -> Result<Scalar, OptimizeError>, jacobian: impl Fn(&X) -> Result<J, OptimizeError>, argument: &X, decrement: &X, step_size: &Scalar, ) -> Result<Scalar, OptimizeError>

where J: Jacobian, for<'a> &'a J: From<&'a X>, X: Solution, for<'a> &'a X: Mul<Scalar, Output = X>,

Trait Implementations

impl Debug for LineSearch

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

Formats the value using the given formatter.

impl Default for LineSearch

fn default() -> Self

Returns the “default value” for a type.
