[−][src]Struct abi_stable::sabi_types::CmpIgnored
Wrapper type used to ignore its contents in comparisons.
Use this if you want to derive trait while ignoring the contents of fields in the
PartialEq
/Eq
/PartialOrd
/Ord
/Hash
traits.
It also replaces the hash of T with the hash of ()
.
Example
This example defines a struct with a CmpIgnored
field.
use abi_stable::sabi_types::CmpIgnored; use std::collections::HashSet; #[derive(Debug,Clone,PartialEq,Eq,PartialOrd,Ord,Hash)] pub struct User{ name:String, surname:String, alt_name:CmpIgnored<String>, } let a=User{ name:"J__n".to_string(), surname:"E____t".to_string(), alt_name:"Z______l P______d".to_string().into(), }; let b=User{ name:"J__n".to_string(), surname:"E____t".to_string(), alt_name:"H___ of B_____".to_string().into(), }; assert_eq!(a,b); let mut map=HashSet::new(); map.replace(a.clone()); assert_eq!( map.replace(b.clone()).unwrap().alt_name.as_str(), "Z______l P______d" ); assert_eq!(map.len(),1); assert_eq!( map.get(&a).unwrap().alt_name.as_str(), "H___ of B_____" );
