Enum TapeOp

    Const(f64),
    Var(usize),

    Div(usize, usize),

    },
}

One operation in the flattened tape. Operand fields are tape-slot indices into the same tape; Var(i) references problem variable index i (read from the input x slice during forward).

Variants

Const(f64)

Var(usize)

Add(usize, usize)

Sub(usize, usize)

Mul(usize, usize)

Div(usize, usize)

Pow(usize, usize)

Neg(usize)

Abs(usize)

Sqrt(usize)

Exp(usize)

Log(usize)

Log10(usize)

Sin(usize)

Cos(usize)

Funcall

AMPL imported (external) function call. The library is kept alive by the Arc; name is the registered function name; args carries positional arguments where real-valued args reference earlier tape slots and string args are inline literals.

Fields

lib: Arc<ExternalLibrary>

name: String

args: Vec<TapeFuncallArg>

Trait Implementations

impl Clone for TapeOp

fn clone(&self) -> TapeOp

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

Performs copy-assignment from source.

impl Debug for TapeOp

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

Formats the value using the given formatter.
