Struct tokenizer_lib::StaticTokenChannel

pub struct StaticTokenChannel<T: PartialEq, TData> { /* fields omitted */ }

A synchronous "channel" which can be used as a sender and reader. Will buffer all tokens into a VecDeque before reading

impl<T: PartialEq, TData> StaticTokenChannel<T, TData>

pub fn new() -> Self

Trait Implementations

impl<T: PartialEq, TData> TokenReader<T, TData> for StaticTokenChannel<T, TData>

fn peek(&self) -> Option<&Token<T, TData>>

Returns reference to next token but does not advance iterator forward

fn next(&mut self) -> Option<Token<T, TData>>

Returns token and advances forward

fn scan(&self, cb: impl FnMut(&T) -> bool) -> Option<&Token<T, TData>>

Runs the closure over the upcoming tokens. Passes the value behind the Token to the closure. Will stop and return a reference to the next Token from when the closure returns true. Returns None if reader finishes before closure returns true. Does not advance the reader.

fn expect_next(
    &mut self,
    expected_type: T
) -> Result<TData, Option<(T, Token<T, TData>)>>

Tests that next token matches an expected type. Will return error if does not match. The ok value contains the data of the valid token. Else it will return the Err with the expected token type and the token that did not match

impl<T: PartialEq, TData> TokenSender<T, TData> for StaticTokenChannel<T, TData>

fn push(&mut self, token: Token<T, TData>)

Appends new Token
