Expand description

Backend implementation for handlers.

Required Methods§

Source

fn write_key(&self, key: &str, writer: &mut W) -> Result<()>

Write the provided key.

Source

fn write_handler(&self, handler: &HandlerCodegen, writer: &mut W) -> Result<()>

Write the provided handler.

Source

fn begin_nested(&self, root: bool, writer: &mut W) -> Result<()>

Begin a nested handler.

If root is true, then this is the first nesting.

Source

fn end_nested(&self, root: bool, writer: &mut W) -> Result<()>

End a nested handler.

If root is true, then this is the first nesting.

Provided Methods§

Source

fn begin(&self, writer: &mut W) -> Result<()>

Optional hook which will be called at the start of this stage.

Source

fn end(&self, writer: &mut W) -> Result<()>

Optional hook which will be called at the end of this stage.
