Struct serde_path_to_error::Serializer [−][src]
pub struct Serializer<'a, 'b, S> { /* fields omitted */ }
Expand description
Serializer adapter that records path to serialization errors.
Example
use serde::Serialize;
use std::collections::BTreeMap;
// Maps with a non-string key are not valid in JSON.
let mut inner_map = BTreeMap::new();
inner_map.insert(vec!['w', 'a', 't'], 0);
let mut outer_map = BTreeMap::new();
outer_map.insert("k", inner_map);
// Some Serializer.
let mut out = Vec::new();
let jser = &mut serde_json::Serializer::new(&mut out);
let mut track = serde_path_to_error::Track::new();
let ps = serde_path_to_error::Serializer::new(jser, &mut track);
match outer_map.serialize(ps) {
Ok(_) => panic!("expected failure to serialize non-string key"),
Err(_) => {
let path = track.path().to_string();
assert_eq!(path, "k");
}
}
Implementations
Trait Implementations
The output type produced by this Serializer
during successful
serialization. Most serializers that produce text or binary output
should set Ok = ()
and serialize into an io::Write
or buffer
contained within the Serializer
instance. Serializers that build
in-memory data structures may be simplified by using Ok
to propagate
the data structure around. Read more
