Index out of bounds

[leontoeides]

When I initialize the Bloom2 filter like so:

let mut bloom_filter: Bloom2<RandomState, CompressedBitmap, MyStruct> = BloomFilterBuilder::default()
    .size(FilterSize::KeyBytes4)
    .build();

I receive the following error when my program is run:

The application panicked (crashed).
Message:  index out of bounds: the len is 16 but the index is 275465
Location: C:\Users\User Name\.cargo\registry\src\github.jparrowsec.cn-1ecc6299db9ec823\bloom2-0.2.0\src\bitmap\compressed_bitmap.rs:254

However, if I initialize like this:

let mut bloom_filter: Bloom2<RandomState, CompressedBitmap, MyStruct> = Bloom2::default();

It works well. Nice and fast!

If you require more detail, let me know!

Hey @leontoeides

Thanks for reporting this!

It was an oversight with the BloomFilterBuilder::size() method - it would set the key size used by the filter but not expand the underlying bitmap size. This has been fixed in 1105e7a by resizing the underlying bitmap when using the CompressedBitmap implementation :)

Again, thanks for reporting this, it's really appreciated and I am truly pleased you have found the crate useful! 👍

I have pushed v0.2.1 containing this fix to crates.io 👍

That was fast! Thank you so much
