# `ExDataSketch.Errors.FilterFullError`
[🔗](https://github.com/thanos/ex_data_sketch/blob/main/lib/ex_data_sketch/errors.ex#L117)

Raised by a bang function (`put!/2`, and so on) when the underlying
filter has no capacity left for the insertion, e.g. `ExDataSketch.Cuckoo`
exhausting its relocation budget, or an `ExDataSketch.FilterChain` stage
reporting `{:error, :full}`. The non-bang counterpart returns
`{:error, :full}` (or `{:error, :full, partial}`) instead of raising.
