Function serde_json::ser::to_writer

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

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

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