Compact inlined strings.
String type that's source compatible with
std::string::String, uses exactly the same amount of
space, doesn't heap allocate for short strings (up to 23 bytes on 64-bit archs) by storing them in
the space a
String would have taken up on the stack, making strings go faster overall.
This crate provides a wrapper for Rust's standard
String which uses the space a
on the stack to store inline string data, automatically promoting it to a
String when it grows
beyond the inline capacity. This has the advantage of avoiding heap allocations for short strings as
well as improving performance thanks to keeping the strings on the stack.
This is all accomplished without the need for an external discriminant, so a
exactly the same size as a
String on the stack, regardless of whether it's inlined or not, and
when not inlined it's pointer compatible with
String, meaning that you can safely coerce a
SmartString to a
pointer::cast() and go on using it as
if it had never been a
SmartString. (But please don't do that, there's an
implementation that's much safer.)
