Crate zero [] [src]

Functions for reading binary data into Rust data structures. All functions are zero-allocation.

There are functions for reading a single value, an array of values, a single null-terminated utf8 string (which should also work with ascii strings), and an array of null-terminated strings terminated by another null byte.

Functions preserve the lifetime of the underlying data. These functions are memory safe, although this is in part based on the assumption that the client only implements the unsafe trait Pod where safe to do so.

Functions assert that the provided data is large enough. The string functions check that strings are valid utf8. There is no checking that the the privided input will produce a valid object (for example, an enum has a valid discriminant). The user must assert this by implementing the trait Pod.

There are also unsafe versions of most functions which do not require the return type to implement Pod and which do no checking.



Iterates over, yielding strings (null-terminated in See read_strs_to_null.



Implementing this trait means that the concrete type is plain old data (POD). Precisely, by implementing Pod the programmer asserts that it is safe to read the type from binary slices provided to read, etc.



Reads a single T from input.


Read an array of Ts from input.


Reads an array of Ts from input with no checks.


Read a string from input. The string must be a null-termianted utf8 string. Note that an ascii C string fulfils this requirement.


Reads a null-terminated string from input with no checks.


Returns an iterator which will return a sequence of strings from input. Each string must be a null-terminated utf8 string. The sequence of strings is terminated either by a second null byte, or the end of input.


Reads a T from input with no checks.
