Trait serde_json::ser::Formatter
[−]
[src]
pub trait Formatter { fn open<W>(&mut self, writer: &mut W, ch: u8) -> Result<()> where W: Write; fn comma<W>(&mut self, writer: &mut W, first: bool) -> Result<()> where W: Write; fn colon<W>(&mut self, writer: &mut W) -> Result<()> where W: Write; fn close<W>(&mut self, writer: &mut W, ch: u8) -> Result<()> where W: Write; }
This trait abstracts away serializing the JSON control characters, which allows the user to optionally pretty print the JSON output.

fn open<W>(&mut self, writer: &mut W, ch: u8) -> Result<()> where W: Write
Called when serializing a '{' or '['.

fn close<W>(&mut self, writer: &mut W, ch: u8) -> Result<()> where W: Write
