Pull request overview
This PR fixes a critical double-free issue in the Node.js bindings under high-concurrency conditions by changing the decode_buffer function to accept a BufferSlice instead of an owned Buffer.
Changes:
- Changed parameter type from
BuffertoBufferSliceindecode_buffermethod - Updated the import to use
BufferSliceinstead ofBuffer - Simplified buffer usage from
buffer.to_vec().as_slice()to&buffer(more efficient as it avoids copying)

As a non-async function,
decode_bufferdoesn't require owning theBufferand can do with only aBufferSlice. This takes the cleanup responsibility fromnapi-rsand should prevent the double free scenarios, as theBufferis now Node runtime-managed.Closes #368
