[−][src]Struct serde_with::BytesOrString
Deserialize from bytes or string
Any Rust String
can be converted into bytes, i.e., Vec<u8>
.
Accepting both as formats while deserializing can be helpful while interacting with language
which have a looser definition of string than Rust.
Example
#[serde_as] #[derive(Deserialize, Serialize)] struct A { #[serde_as(as = "BytesOrString")] bytes_or_string: Vec<u8>, } // Here we deserialize from a byte array ... let j = json!({ "bytes_or_string": [ 0, 1, 2, 3 ] }); let a: A = serde_json::from_value(j.clone()).unwrap(); assert_eq!(vec![0, 1, 2, 3], a.bytes_or_string); // and serialization works too. assert_eq!(j, serde_json::to_value(&a).unwrap()); // But we also support deserializing from a String let j = json!({ "bytes_or_string": "✨Works!" }); let a: A = serde_json::from_value(j).unwrap(); assert_eq!("✨Works!".as_bytes(), &*a.bytes_or_string);
