-//! A simple non-reference counted string that uses small string optimization (SSO).
-//!
-//! This string has 3 allocation possibilities:
-//!
-//! 1. Small - embedded buffer is used for up to `kSSOCapacity` characters.
-//! This should handle most small strings and thus avoid dynamic
-//! memory allocation for most use-cases.
-//!
-//! 2. Large - string that doesn't fit into an embedded buffer (or string
-//! that was truncated from a larger buffer) and is owned by
-//! AsmJit. When you destroy the string AsmJit would automatically
-//! release the large buffer.
-//!
-//! 3. External - like Large (2), however, the large buffer is not owned by
-//! AsmJit and won't be released when the string is destroyed
-//! or reallocated. This is mostly useful for working with
-//! larger temporary strings allocated on stack or with immutable
-//! strings.
