/** @brief Hash `str` to `hash` for use in a switch case
|
|
*
|
|
* A string needs to be hashed for it to be used
|
|
* inside of a switch statement. We want to use a switch
|
|
* statement instead of an if-else chain for it's
|
|
* simplicity and lower amount of low-level operations.
|
|
*
|
|
* @param str The string to hash
|
|
*
|
|
* @returns hash The hashed version of `str`
