litenum
litenum is the minimal utility for conversion between literal and enum !
Features
- minimal inplementation
- no std, no alloc
How to use
to literal
#[litenum::to]
enum AnkerTarget {
_blank,
_self,
_top,
_parent,
}
fn main() {
assert_eq!(
AnkerTarget::_blank.lit(),
"_blank",
)
}
from literal
#[litenum::from]
#[derive(Debug, PartialEq)]
enum AnkerTarget {
_blank,
_self,
_top,
_parent,
}
fn main() {
assert_eq!(
AnkerTarget::from_lit("_blank"),
Some(AnkerTarget::_blank),
)
}
impl both at once
#[litenum::ium] // same as
// `#[litenum::to] #[litenum::from]`
#[derive(Debug, PartialEq)]
enum AnkerTarget {
_blank,
_self,
_top,
_parent,
}
fn main() {
assert_eq!(
AnkerTarget::_blank.lit(),
"_blank",
);
assert_eq!(
AnkerTarget::from_lit("_blank"),
Some(AnkerTarget::_blank),
);
}
