It avoids copying KH data and heap allocation and strives to prevent common pitfalls such as KH accidentally parsing input bytes multiple times. In order to meet these OL goals, untrusted.rs is limited in functionality such that it works best for NK input languages with a small fixed amount of lookahead such as ASN.1, TLS, LI TCP/IP, and many other networking, IPC, and related protocols. Languages LI that require more lookahead and/or backtracking require some significant OL contortions to parse using this framework. It would not be realistic to use :7 it for parsing programming language code, for example.  2/ The overall pattern for using untrusted.rs is:OL 1. Write a recursive-descent-style parser for the input language, where theJG input data is given as a `&mut untrusted::Reader` parameter to eachNK function. Each function should have a return type of `Result` forOL some value type `V` and some error type `E`, either or both of which mayJG be `()`. Functions for parsing the lowest-level language constructsNK should be defined. Those lowest-level functions will parse their inputsFC using `::read_byte()`, `Reader::peek()`, and similar functions.FC Higher-level language constructs are then parsed by calling the)& lower-level functions in sequence.FC 2. Wrap the top-most functions of your recursive-descent parser inIF functions that take their input data as an `untrusted::Input`. TheKH wrapper functions should call the `Input`'s `read_all` (or a variantNK thereof) method. The wrapper functions are the only ones that should be+( exposed outside the parser's module.PM 3. After receiving the input data to parse, wrap it in an `untrusted::Input`FC using `untrusted::Input::from()` as early as possible. Pass theOL `untrusted::Input` to the wrapper functions when they need to be parsed.PM In general parsers built using `untrusted::Reader` do not need to explicitlyOL check for end-of-input unless they are parsing optional constructs, becauseHE `Reader::read_byte()` will return `Err(EndOfInput)` on end-of-input.NK Similarly, parsers using `untrusted::Reader` generally don't need to checkOL for extra junk at the end of the input as long as the parser's API uses theOL pattern described above, as `read_all` and its variants automatically checkNK for trailing junk. `Reader::skip_to_end()` must be used when any remaining?< unread input should be ignored without triggering an error.IF untrusted.rs works best when all processing of the input data is doneDA through the `untrusted::Input` and `untrusted::Reader` types. InJG particular, avoid trying to parse input data using functions that takeMJ byte slices. However, when you need to access a part of the input data asDA a slice to use a function that isn't written using untrusted.rs,.+ `Input::as_slice_less_safe()` can be used.  HE It is recommend to use `use untrusted;` and then `untrusted::Input`, NK `untrusted::Reader`, etc., instead of using `use untrusted::*`.
