Crate macro_helper

This crate is a collection of ligthweight procedural macros typically used for writing others,either procedural or not,as such covers some of the missing features you might expect from macro_rules! like expansion bucles controlled by you and not an input.Or guarantee an identifier is borrowed in the manner you want over any other,included own.

This crate is no_std.

Macros

Stringify	Stringify the input.
as_mut_ref_token	Ensures that the reference or identifier passed is mutable and changes it if is not.
as_ref_token	Ensures that the reference or identifier passed is shared and changes it if is not.
count_spec_tokens	Expands to the number of spec tokens you pass in tokens => spec syntax,useful when expanding expansion bucles with a given separator matched in spec;to retrieve the number of expansions,as it have more precedence than the other macros.
count_tokens	Expands to the number of tokens you pass.
eval_encoded	Eval encoded strings that maybe are from other macros.
expansion_bucle	An expansion bucle with syntax code => num when num is the number of times the code should be expanded.
expansion_bucle_counted	An expansion bucle with syntax code => num when num is the number of times the code should be expanded along with a replacement of the rep_count imaginary variable at each "iteration" with values from 0 thought num-1.
proto	This macro panics with the message "Prototype reached 'tokens'." where tokens are the tokens passed.
