Enum arithmetic_eval::Function

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

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§

source§

impl<T> Function<T>

source

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

Creates a native function.

source

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

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

source§

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

source

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

Evaluates the function on the specified arguments.

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

source§

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

Performs the conversion.
source§

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

source§

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