Trait Implementations

impl<'a> Debug for WastVal<'a>

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

Formats the value using the given formatter.

impl<'a> Parse<'a> for WastVal<'a>

fn parse(parser: Parser<'a>) -> Result<Self>

Attempts to parse Self from parser, returning an error if it could not be parsed.

impl Peek for WastVal<'_>

fn peek(cursor: Cursor<'_>) -> Result<bool>

Tests to see whether this token is the first token within the Cursor specified.

fn display() -> &'static str

Returns a human-readable name of this token to display when generating errors about this token missing.

fn peek2(cursor: Cursor<'_>) -> Result<bool>

The same as peek, except it checks the token immediately following the current token.
