Enum Op 

pub enum Op {
    Input(Var),
    Const(OrderedFloat<f64>),
    Binary(BinaryOpcode, Node, Node),
    Unary(UnaryOpcode, Node),
}

An operation in a math expression

Ops should be constructed by calling functions on Context, e.g. Context::add will generate an Op::Binary(BinaryOpcode::Add, .., ..) node and return an opaque handle.

Each Op is tightly coupled to the Context which generated it, and will not be valid for a different Context.

Variants

Input(Var)

Const(OrderedFloat<f64>)

Binary(BinaryOpcode, Node, Node)

Unary(UnaryOpcode, Node)

Implementations

impl Op

pub fn dot_node_color(&self) -> &str

Returns the color to be used in a GraphViz drawing for this node

pub fn dot_node_shape(&self) -> &str

Returns the shape to be used in a GraphViz drawing for this node

pub fn iter_children(&self) -> impl Iterator<Item = Node>

Iterates over children, producing 0, 1, or 2 values

pub fn dot_edges(&self, i: Node) -> String

Returns a GraphViz string of edges from this node to its children

pub fn dot_edge(&self, a: Node, b: Node, alpha: &str) -> String

Returns a single edge with user-specified transparency

Trait Implementations

impl Clone for Op

fn clone(&self) -> Op

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Op

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

Formats the value using the given formatter.

impl Hash for Op

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 Ord for Op

fn cmp(&self, other: &Op) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Op

fn eq(&self, other: &Op) -> 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.

impl PartialOrd for Op

fn partial_cmp(&self, other: &Op) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
