This library resulted from improving the functionality for working
with null-terminated strings that was formerly provided by Rust module
std::c_str. Earlier revisions of this work were submitted as an
RFC for inclusion in the Rust
distribution, but a more conservative redesign has been selected instead.
Nonetheless, this c_str crate provides memory management helpers
for foreign-allocated null-terminated strings, as well as performance-minded
conversion methods for producing null-terminated strings out of built-in Rust
strings and related data types. If your code involves a lot of passing string
data between C-style APIs and Rust, you may want to give this library a try.
