v0.14.0 - 2021/10/27

Added

• Added the new BufferBackend string interner backend.
  • This backend focuses on minimum memory consumption and allocations
    at the costs of decreased symbol resolution performance.
  • Use this when memory consumption is your main concern.
• Added example of how to use a different string interner backend or symbol.
• Added library docs comparing all the different string interner backends.

Changed

• The string_interner crate now uses the Rust 2021 edition.
• The DefaultBackend now is the StringBackend and no longer the BucketBackend.
• The generic S symbol parameter of all string interner backends
  now defaults to the DefaultSymbol.
• The Backend trait is no longer generic over a symbol S but instead
  has a Symbol associated type now.
• The StringInterner no longer has a generic S symbol parameter and
  now instead uses the Symbol associated type from its used backend B.

Dev. Note

• The memory_consumption tests now shrink the string interners before querying
  their memory consumption. This yields more stable numbers than before.
• The memory_consumption test now also tests the total amount of allocations
  and deallocations made by the string interner backends.
• Add README section about benchmarking the crate.
