}Expand description
Defines common methods that would exist on a AST part include position in source, creation from reader and serializing to string from settings.

Required Methods§
sourcefn get_position(&self) -> Cow<'_, Span>
fn get_position(&self) -> Cow<'_, Span>
Returns position of node as span AS IT WAS PARSED. May be none if AST was doesn’t match anything in source
fn from_reader( reader: &mut impl TokenReader<TSXToken, Span>, state: &mut ParsingState, settings: &ParseSettings ) -> ParseResult<Self>
fn to_string_from_buffer<T: ToString>( &self, buf: &mut T, settings: &ToStringSettingsAndData, depth: u8 )
Provided Methods§
sourcefn from_string(
source: String,
settings: ParseSettings,
source_id: SourceId,
offset: Option<usize>,
cursors: Vec<(usize, EmptyCursorId)>
) -> ParseResult<ParseOutput<Self>>
fn from_string( source: String, settings: ParseSettings, source_id: SourceId, offset: Option<usize>, cursors: Vec<(usize, EmptyCursorId)> ) -> ParseResult<ParseOutput<Self>>
From string, with default impl to call abstract method from_reader
sourcefn to_string(&self, settings: &ToStringSettingsAndData) -> String
fn to_string(&self, settings: &ToStringSettingsAndData) -> String
Returns structure as valid string
