Trait implemented by all implementors of MaybeStrings but NoStrings

Required Methods§

Source

fn message(&self) -> PropertiesResult<'_, &[u8], Self>

Returns an array with all messages, separated by b'\n'

Source

fn message_offset( &self, node: NodeId, ) -> PropertiesResult<'_, Option<u64>, Self>

Returns the position of the first character of node’s message in Self::message, or None if it is out of bound, or Some(u64::MAX) if the node has no message

Source

fn tag_name(&self) -> PropertiesResult<'_, &[u8], Self>

Returns an array with all messages, separated by b'\n'

Source

fn tag_name_offset( &self, node: NodeId, ) -> PropertiesResult<'_, Option<u64>, Self>

Returns the position of the first character of node’s tag_name in Self::tag_name, or None if it is out of bound, or Some(u64::MAX) if the node has no tag_name
