String Interner

A data structure to cache strings efficiently, with minimal memory footprint and the ability to assicate the interned strings with unique symbols. These symbols allow for constant time comparisons and look-ups to the underlying interned string contents. Also, iterating through the interned strings is cache efficient.

Testing

Test the project using

cargo test --release

Memory Allocation Tests

To further test memory consumption and allocations performed by the different string interner backends test the project as follows:

cargo test --release --features test-allocations -- --test-threads 1

• The --features test-allocations enables the memory allocations tests.
• The --test-thread 1 argument is required for the memory allocations tests since otherwise they interfere with each other causing them to randomly fail.
• Use --nocapture to receive verbose output useful for debugging.

Profiling & Benchmarks

Benchmark the string interner and its various backends using
