 Contract data is associated with a key, which can be used at a later time to look up the value.
 
-`Symbol` is a short (up to 32 characters long) string type with limited character space (only `a-zA-z0-9_` characters are allowed). Identifiers like contract function names and contract data keys are represented by `Symbol`s.

 The `symbol_short!()` macro is a convenient way to pre-compute short symbols up to 9 characters in length at compile time using `Symbol::short`. It generates a compile-time constant that adheres to the valid character set of letters (a-zA-Z), numbers (0-9), and underscores (\_). If a symbol exceeds the 9-character limit, `Symbol::new` should be utilized for creating symbols at runtime.
