This commit adds 'i lifetime that can be used by backends to return &'i str when it's known that the backing string storage won't be moved. This is the case for fixed capacity pool-like backends and backends which avoid backing buffer moves via double indirection. Signed-off-by: Tin Švagelj <[email protected]>

This commit adds 'i lifetime that can be used by backends to return &'i str when it's known that the backing string storage won't be moved.
This is the case for fixed capacity pool-like backends and backends which avoid backing buffer moves via double indirection.
StringInterner::resolvecan now return&'i strfor backends that support it, or a local (call-site bound) reference. The local reference prevents insertions intoStringInternerdue to XOR mutability, while&'i strdoesn't.This is related to #75.
TODO
'ilifetimeBucketBackendso it's capable of resolving to&'i str.
