Expand description

This trait abstracts away serializing the JSON control characters

Required Methods§

Source

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

Called when serializing a ‘{’ or ‘[’.

Source

fn comma<W>(&mut self, writer: &mut W, first: bool) -> Result<()>
where W: Write,

Called when serializing a ‘,’.

Source

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

Called when serializing a ‘:’.

Source

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

Called when serializing a ‘}’ or ‘]’.

Source

fn newline<W>(&mut self, writer: &mut W, add_indent: i32) -> Result<()>
where W: Write,

Newline with indent.

Source

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

Start a value.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
