Tools to iterate over the values of a type.

Examples

use enum_iterator::{all, cardinality, first, last, next, previous, reverse_all,Sequence};#[derive(Debug,PartialEq,Sequence)]enumDay{Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday}assert_eq!(cardinality::<Day>(),7);assert_eq!(all::<Day>().collect::<Vec<_>>(),[Day::Monday,Day::Tuesday,Day::Wednesday,Day::Thursday,Day::Friday,Day::Saturday,Day::Sunday,]);assert_eq!(first::<Day>(),Some(Day::Monday));assert_eq!(last::<Day>(),Some(Day::Sunday));assert_eq!(next(&Day::Tuesday),Some(Day::Wednesday));assert_eq!(previous(&Day::Wednesday),Some(Day::Tuesday));assert_eq!(reverse_all::<Day>().collect::<Vec<_>>(),[Day::Sunday,Day::Saturday,Day::Friday,Day::Thursday,Day::Wednesday,Day::Tuesday,Day::Monday,]);

use enum_iterator::{cardinality, first, last,Sequence};#[derive(Debug,PartialEq,Sequence)]structFoo{a:bool,b:u8,}assert_eq!(cardinality::<Foo>(),512);assert_eq!(first::<Foo>(),Some(Foo{ a:false, b:0}));assert_eq!(last::<Foo>(),Some(Foo{ a:true, b:255}));
