Enum genie_support::StringKey

pub enum StringKey {
    Num(u32),
    Name(String),
}

A key in a language file.

A key may be either a nonnegative integer or an arbitrary string.

The original game supports only nonnegative integers. The HD Edition allows for integers as well as Strings to serve as keys in a key value file.

Variants

Num(u32)

An integer string key.

Name(String)

A named string key. The string must not represent a u32 value (such keys must be Num).

Implementations

impl StringKey

pub fn is_numeric(&self) -> bool

Returns true if and only if this StringKey is a number.

Examples

use genie_support::StringKey;
use std::convert::TryFrom;
assert!(StringKey::try_from(0).unwrap().is_numeric());
assert!(!StringKey::from("").is_numeric());

pub fn is_named(&self) -> bool

Returns true if and only if this StringKey is a string name.

Examples

use genie_support::StringKey;
use std::convert::TryFrom;
assert!(!StringKey::try_from(0).unwrap().is_named());
assert!(StringKey::from("").is_named());
