pub struct SerializeDescriptors<'a, T: Serialize>(&'a T, Cell<Vec<RawDescriptor>>);
Expand description

Wrapper for a Serialize value which will capture any descriptors exported by the value when given to an ordinary Serializer.

This is the corresponding type to use for serialization before using deserialize_with_descriptors.

§Examples

use serde_json::to_string;
use base::{FileSerdeWrapper, SerializeDescriptors};
use tempfile::tempfile;

let tmp_f = tempfile().unwrap();
let data = FileSerdeWrapper(tmp_f);
let data_wrapper = SerializeDescriptors::new(&data);

// Serializes `v` as normal...
let out_json = serde_json::to_string(&data_wrapper).expect("failed to serialize");
// If `serialize_descriptor` was called, we can capture the descriptors from here.
let out_descriptors = data_wrapper.into_descriptors();
