Expand description
A selector expression with existing operations
Variants§
In(String, BTreeSet<String>)
Key exists and in set:
let exp = Expression::In("foo".into(), ["bar".into(), "baz".into()].into());
assert_eq!(exp.to_string(), "foo in (bar,baz)");
let exp = Expression::In("foo".into(), ["bar".into(), "baz".into()].into_iter().collect());
assert_eq!(exp.to_string(), "foo in (bar,baz)");
NotIn(String, BTreeSet<String>)
Key does not exists or not in set:
let exp = Expression::NotIn("foo".into(), ["bar".into(), "baz".into()].into());
assert_eq!(exp.to_string(), "foo notin (bar,baz)");
let exp = Expression::NotIn("foo".into(), ["bar".into(), "baz".into()].into_iter().collect());
assert_eq!(exp.to_string(), "foo notin (bar,baz)");
Equal(String, String)
Key exists and is equal:
let exp = Expression::Equal("foo".into(), "bar".into());
assert_eq!(exp.to_string(), "foo=bar")
NotEqual(String, String)
Key does not exists or is not equal:
let exp = Expression::NotEqual("foo".into(), "bar".into());
assert_eq!(exp.to_string(), "foo!=bar")
Exists(String)
Key exists:
let exp = Expression::Exists("foo".into());
assert_eq!(exp.to_string(), "foo")
DoesNotExist(String)
Key does not exist:
let exp = Expression::DoesNotExist("foo".into());
assert_eq!(exp.to_string(), "!foo")
