Trait Implementations

impl<'a> Clone for RefType<'a>

fn clone(&self) -> RefType<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for RefType<'a>

impl<'a> Debug for RefType<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for RefType<'a>

impl<'a> Hash for RefType<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<'a> Parse<'a> for RefType<'a>

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

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

impl<'a> PartialEq<RefType<'a>> for RefType<'a>

fn eq(&self, other: &RefType<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &RefType<'a>) -> bool

This method tests for !=.

impl<'a> Peek for RefType<'a>

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

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