Enum arithmetic_eval::Function

pub enum Function<T> {
    Native(Arc<dyn NativeFn<T>>),
    Interpreted(Arc<InterpretedFn<T>>),
}

Function definition. Functions can be either native (defined in the Rust code) or defined in the interpreter.

Variants

Native(Arc<dyn NativeFn<T>>)

Native function.

Interpreted(Arc<InterpretedFn<T>>)

Interpreted function.

Implementations

impl<T> Function<T>

pub fn native(function: impl NativeFn<T> + 'static) -> Self

Creates a native function.

pub fn is_same_function(&self, other: &Self) -> bool

Checks if the provided function is the same as this one.

impl<T: 'static + Clone> Function<T>

pub fn evaluate( &self, args: Vec<SpannedValue<T>>, ctx: &mut CallContext<'_, T> ) -> EvalResult<T>

Evaluates the function on the specified arguments.

Trait Implementations

impl<T> Clone for Function<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Function<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for Function<T>

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

Formats the value using the given formatter.

impl<T> IntoEvalResult<T> for Function<T>

fn into_eval_result(self) -> Result<Value<T>, ErrorOutput>

Performs the conversion.

impl<T: PartialEq> PartialEq<Function<T>> for Function<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> TryFromValue<T> for Function<T>

fn try_from_value(value: Value<T>) -> Result<Self, FromValueError>

Attempts to convert value to a type supported by the function.
