Struct TokensRemain 

pub struct TokensRemain;

Succeeds only when tokens remain in the stream.

Examples

use unsynn::*;
use unsynn::predicates::*;

let mut tokens = "foo".to_token_iter();
assert!(TokensRemain::parse(&mut tokens).is_ok());

let mut empty = "".to_token_iter();
assert!(TokensRemain::parse(&mut empty).is_err());

Trait Implementations

impl Clone for TokensRemain

fn clone(&self) -> TokensRemain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokensRemain

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

Formats the value using the given formatter.

impl Default for TokensRemain

fn default() -> TokensRemain

Returns the “default value” for a type.

impl Parser for TokensRemain

fn parser(tokens: &mut TokenIter) -> Result<TokensRemain, Error>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl ToTokens for TokensRemain

fn to_tokens(&self, _tokens: &mut TokenStream)

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
