Struct diceprop::Fun1

pub struct Fun1<'a, F> {
    pub name: &'a str,
    // some fields omitted
}

Represents a function of arity 1.

Fields

name: &'a str

The name of the function.

Implementations

impl<'a, F> Fun1<'a, F>

pub fn new(name: &'a str, f: F) -> Self

Creates a Fun1 with the given name and prefix syntax (e.g. f(x)).

pub fn postfix(name: &'a str, f: F) -> Self

Creates a Fun1 with the given name and postfix syntax (e.g. (x)!).

pub fn eval<AL1, AV1, RV>(
    &self,
    arg_1: Eval<AL1, AV1>
) -> Eval<Fun1Label<'a, AL1>, RV> where
    AL1: Display + Copy,
    RV: Debug,
    F: Fn(AV1) -> RV, 

Returns an Eval that contains the result of the function applied to the given argument.

This operation will log the function application via dicetest::hints.

pub fn eval_once<AL1, AV1, RV>(
    self,
    arg_1: Eval<AL1, AV1>
) -> Eval<Fun1Label<'a, AL1>, RV> where
    AL1: Display + Copy,
    RV: Debug,
    F: FnOnce(AV1) -> RV, 

Returns an Eval that contains the result of the function applied to the given argument.

This operation will log the function application via dicetest::hints.

pub fn as_ref<'b>(&'b self) -> Fun1<'a, &'b F>

Returns an Fun1 with the same name and syntax and a reference to the original function.
