Trait Implementations

impl Clone for TryOrNil

fn clone(&self) -> TryOrNil

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TryOrNil

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TryOrNil

fn eq(&self, other: &TryOrNil) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TokenizeInto for TryOrNil

fn tokenize_into(&self, tokens: &mut VecDeque<Ranged<Token>>)

Tokenize self into tokens.

fn to_tokens(&self) -> VecDeque<Ranged<Token>>

Returns a list of tokens that could be re-parsed to produce this value.
