Metainfo
Transmissing metainfo across components.
Quickstart
Metainfo is designed to be passed through task local, so we provided a unified key for it metainfo::METAINFO
, and we recommend you to use it this way:
METAINFO.scope(...)
MetaInfo
is used to passthrough information between components and even client-server.
It supports two types of info: typed map and string k-v.
It is designed to be tree-like, which means you can share a MetaInfo
with multiple children.
Note: only the current scope is mutable.
Example:
use metainfo::MetaInfo;
fn test() {
let mut m1 = MetaInfo::new();
m1.insert::<i8>(2);
assert_eq!(*m1.get::<i8>().unwrap(), 2);
let (mut m1, mut m2) = m1.derive();
assert_eq!(*m2.get::<i8>().unwrap(), 2);
m2.insert::<i8>(4);
assert_eq!(*m2.get::<i8>().unwrap(), 4);
m2.remove::<i8>();
assert_eq!(*m2.get::<i8>().unwrap(), 2);
}
