Struct StderrLog 

pub struct StderrLog<T, const N: usize = 5>(/* private fields */);

A no-op debug parser that does nothing when the debug_grammar feature is disabled.

This type becomes a zero-sized type that doesn’t parse anything and has no runtime cost. It exists only to maintain API compatibility when debug output is disabled.

Trait Implementations

impl<T, const N: usize> Parser for StderrLog<T, N>

fn parser(_tokens: &mut TokenIter) -> Result<StderrLog<T, N>, 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<T, const N: usize> ToTokens for StderrLog<T, N>

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.
