Function serde_json::to_writer

pub fn to_writer<W, T>(writer: W, value: &T) -> Result<()>where
    W: Write,
    T: ?Sized + Serialize,

Serialize the given data structure as JSON into the IO stream.

Serialization guarantees it only feeds valid UTF-8 sequences to the writer.

Errors

Serialization can fail if T’s implementation of Serialize decides to fail, or if T contains a map with non-string keys.
