API

Functions (fn.d.ts)

• FnArity1<T1, R> - A type representing a function with an arity of 1, or a function that takes 1 argument (T1) and a return type of R.
• FnArity2<T1, T2, R> - A type representing a function with an arity of 2, or a function that takes 2 arguments (T1, T2) and a return type of R.
• FnArity3<T1, T2, T3, R> - A type representing a function with an arity of 3, or a function that takes 3 arguments (T1, T2, T3) and a return type of R.
• FnArity4<T1, T2, T3, T4, R> - A type representing a function with an arity of 4, or a function that takes 4 arguments (T1, T2, T3, T4) and a return type of R.
• PredicateFnArity1<T1> - A type representing a predicate function with an arity of 1, or a function that takes 1 argument (T1) and returns a boolean.
• PredicateFnArity2<T1, T2> - A type representing a predicate function with an arity of 2, or a function that takes 2 arguments (T1, T2) and returns a boolean.
• PredicateFnArity3<T1, T2, T3> - A type representing a predicate function with an arity of 3, or a function that takes 3 arguments (T1, T2, T3) and returns a boolean.
• PredicateFnArity4<T1, T2, T3, T4> - A type representing a predicate function with an arity of 4, or a function that takes 4 arguments (T1, T2, T3, T4) and returns a boolean.

Logic gates (logic.d.ts)

• Not<A>: A type representing the logical NOT gate of A, or logical negation.
• And<A, B>: A type representing the logical AND gate of A and B, or logical conjunction.
• Or<A, B>: A type representing the logical OR gate of A and B, or logical disjunction.
• Nor<A, B>: A type representing the logical NOR gate of A and B, or logical non-disjunction. A special type of gate that is functionally complete (capable of expressing all possible truth tables).
• Nand<A, B>: A type representing the logical NAND gate of A and B. A special type of gate that is functionally complete (capable of expressing all possible truth tables).
• Xor<A, B>: A type representing the logical XOR gate of A and B, or exclusive disjunction/exclsuive OR.
• Xnor<A, B>: A type representing the logical XNOR gate of A and B, or logical biconditional.

Strings (strings.d.ts)

• Affix: A string union type representing the possible affixes of a string: 'prefix' or 'suffix'. Intended for use with generic types such as AffixedWith or RemoveAffix.
• StartsWith<V, P>: A conditional type representing whether a string value V starts with a prefix P; evaluates to a boolean.
• EndsWith<V, S>: A conditional type representing whether a string value V ends with a suffix S; evaluates to a boolean.
• AffixedWith<V, Lit, A>: A conditional type representing whether a string value V is affixed with an affix Lit with an affix kind of A; evaluates to a boolean.
• PrefixWith<V, Lit>: A template literal type representing the result of prefixing a string value V with a prefix Lit; evaluates to a string literal.
• SuffixWith<V, Lit>: A template literal type representing the result of suffixing a string value V with a suffix S; evaluates to a string literal.
• RemovePrefix<V, Lit>: A template literal type representing the result of removing a prefix Lit from a string value V; evaluates to a string literal.
• RemoveSuffix<V, Lit>: A template literal type representing the result of removing a suffix Lit from a string value V; evaluates to a string literal.
• RemoveAffix<V, Lit, A>: A template literal type representing the result of removing an affix Lit from a string value V with an affix kind of A; evaluates to a string literal.
