Struct FormulaBindings 

pub struct FormulaBindings {
    pub constants: Vec<(String, String)>,
    pub expressions: Vec<(String, String)>,
}

Named literals and sub-formulas declared alongside a formula.

GenApi lets a <SwissKnife>, <IntSwissKnife> or <Converter> name parts of its own formula:

<Constant Name="TEN">10</Constant>
<Expression Name="XPLUS2">TEN + X</Expression>
<Formula>TEN * XPLUS2</Formula>

Both are resolved by substitution when the runtime builds the node, so the evaluator never sees them. Declaration order matters: an <Expression> may refer to constants and to expressions declared before it.

Fields

constants: Vec<(String, String)>

<Constant Name="..">literal</Constant> pairs, in declaration order.

expressions: Vec<(String, String)>

<Expression Name="..">formula</Expression> pairs, in declaration order.

Implementations

impl FormulaBindings

pub fn is_empty(&self) -> bool

Whether nothing was declared.

Trait Implementations

impl Clone for FormulaBindings

fn clone(&self) -> FormulaBindings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormulaBindings

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

Formats the value using the given formatter.

impl Default for FormulaBindings

fn default() -> FormulaBindings

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FormulaBindings

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FormulaBindings

fn eq(&self, other: &FormulaBindings) -> 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 Serialize for FormulaBindings

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for FormulaBindings

impl StructuralPartialEq for FormulaBindings
