rustpython_vm::function::OptionalArg - Rust

An argument that may or may not be provided by the caller.

This style of argument is not possible in pure Python.

impl<T> OptionalArg<T>[src]

pub fn is_present(&self) -> bool[src]

Returns true if self is of variant Present.

pub fn expect_present(self) -> T where
    Self: Debug, [src]

Unwraps the value, yielding the content of Present.

Panics if the value is not Present, with a panic message including the content of self.

pub fn present(self) -> Option<T>[src]

Returns Some if self is of variant Present, and None otherwise.

pub fn is_missing(&self) -> bool[src]

Returns true if self is of variant Missing.
