}Expand description
A trait for defining behavior of adding content to a buffer. As well as register markers for source maps
Required Methods§
Sourcefn push_new_line(&mut self)
fn push_new_line(&mut self)
Append a new line character
Sourcefn push_str(&mut self, string: &str)
fn push_str(&mut self, string: &str)
Use ToString::push_str_contains_new_line if string could contain new lines
Sourcefn push_str_contains_new_line(&mut self, string: &str)
fn push_str_contains_new_line(&mut self, string: &str)
Used to push strings that may contain new lines
Sourcefn add_mapping(&mut self, source_span: &SpanWithSource)
fn add_mapping(&mut self, source_span: &SpanWithSource)
Adds a mapping of the from a original position in the source to the position in the current buffer
Should be called before adding new content
fn characters_on_current_line(&self) -> u32
Provided Methods§
Sourcefn should_halt(&self) -> bool
fn should_halt(&self) -> bool
Some implementors might not ToString the whole input. This signals for users to end early as further usage of this trait has no effect
