Struct Options 

pub struct Options { /* private fields */ }

Implementations

impl Options

pub fn new() -> Self

pub fn insert<S: AsRef<str>>(&mut self, k: S, v: S) -> &Self

pub fn contains_keys<'a>(&self, keys: &'a [String]) -> Vec<&'a str>

pub fn different_set(&self, keys: &[String]) -> Vec<&str>

pub fn pack(&self) -> Option<String>

packs Options, converts Options to String. return None if field ‘inner’ is empty.

use scst::Options;

let mut opt = Options::new();
let s = opt.pack();
assert_eq!(s, None);

opt.insert("a", "b");
assert_eq!(opt.pack(), Some("a=b".to_string()));

pub fn pack_with_check(&self, keys: &[String]) -> Result<Option<String>>

like pack(), but checks input firstly.

use scst::Options;

let mut opt = Options::new();
let s = opt.pack_with_check(&Vec::new());
assert_eq!(s.unwrap(), None);

opt.insert("a", "b");
assert!(opt.pack_with_check(&["c".to_string()]).is_err());
