Expand description

Trait that implements common interface for building message sections

Required Methods§

Source

fn into_target(self) -> MessageTarget

Converts into target

Source

fn get_target(&self) -> &MessageTarget

Returns message target

Source

fn get_target_mut(&mut self) -> &mut MessageTarget

Returns message target

Provided Methods§

Source

fn set_limit(&mut self, limit: usize)

Updates the message’s size limit.

After this method was called, additional data will not be added to the message if that would result in the message exceeding a size of limit bytes. If the message is already larger than limit when the method is called, it will not be truncated. That is, you can never actually set a limit smaller than the current message size.

Note also that the limit only regards the message constructed by the builder itself. If a builder was created atop a buffer that already contained some data, this pre-existing data is not considered.

Returns a reference to the messages header.
