Required Methods

fn token_id(&self) -> TokenId

fn token_type(&self) -> i32

fn channel(&self) -> i32

fn start(&self) -> usize

Zero-based absolute start index measured in Unicode scalar values.

fn stop(&self) -> usize

Zero-based absolute inclusive stop index measured in Unicode scalar values.

fn line(&self) -> usize

One-based source line where the token starts.

fn column(&self) -> usize

Zero-based source column where the token starts, measured in Unicode scalar values from the start of line.

fn text(&self) -> Option<&str>

fn source_name(&self) -> &str

fn start_byte(&self) -> usize

Zero-based absolute start offset measured in UTF-8 bytes.

fn stop_byte(&self) -> usize

Zero-based exclusive end offset measured in UTF-8 bytes.

Provided Methods

fn interval(&self) -> TextInterval

fn byte_span(&self) -> Range<usize>

Zero-based UTF-8 byte span for the token text.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
