Struct tor_config::flatten::FieldExtractor
source · struct FieldExtractor;
Expand description
Stunt “data format” which we use for extracting fields for derived Flattenable
impls
The field extraction works as follows:
- We ask serde to deserialize
$ttype
from aFieldExtractor
- We expect the serde-macro-generated
Deserialize
impl to calldeserialize_struct
- We return the list of fields to match up as an error
