Function lib_xch::handler::handler_api
[−]
[src]
pub fn handler_api<T: CheckedType>(
equation: &str
) -> Result<ResultHandler<Vec<T>>, ErrorHandler<T>>
the API balances the Chemical Equation by equation.
It provides one balanced solution, but it may isn't the most correct solution (because it set all free variables = 1).
If the equation can balance, function would return a T
vector which contains the answer.
If not, it would return handler::ErrorHandler
which contains Delta-3 the parser's result and error message.
Panics
The equation you provided should be a common unbalanced chemical equation which only contains one =
.
- Stack Overflow may cause panic. Because it is using regex-based parser.
- The implement for
PartialOrd
andPartialEq
trait may cause panic. Because it should returnOrdering
.
And in the other failed situation, it'll return a error_message
and contain parser_result
(maybe it is empty).
