Hi All,
Can some point me where i can find examples on how to use
mir-ion YAML
From,

documentation is very sparse, but essentially with mir-ion you
import the different ser/deser packages that you would like to
use. If you for example want to deserialize YAML to a custom
struct, you use
```d
import mir.deser.yaml;
struct CustomStruct
{
string foo;
uint bar;
}
void main()
{
string yamlString = `{foo: str, bar: 4}`;
CustomStruct s = yamlString.deserializeYaml!CustomStruct;
assert(s == S("str", 4));
}
```
If you want to deserialize arbitrary values and introspect them
at runtime, you use `YamlAlgebraic` instead of `CustomStruct`,
which you can think of like std.json : JSONValue, but utilizes
mir's algebraic structures, which work more like std.sumtype.
To convert algebraic values to custom structs later, you use
mir.ion.conv : serde, which basically just internally serializes
the data and deserializes it again (but a little more efficiently)
more deserialization examples in the unittests:

and for serialization you use `serializeYaml` from
`mir.ser.yaml`, see
