pub fn ok(value: f64) -> Self

Create an Ok(f64) result.

pub fn err(err_ptr: *const StringObj) -> Self

Create an Err(*const StringObj) result.

pub fn is_ok(&self) -> bool

pub fn is_err(&self) -> bool

pub fn unwrap_ok(&self) -> f64

Get the Ok value. Caller must check is_ok() first.

pub fn unwrap_err(&self) -> *const StringObj

Get the Err pointer. Caller must check is_err() first.
