# Which issue does this PR close?
Closes #1845.
# Rationale for this change
`comparison` kernel has functions `like` and `nlike`, which perform `LIKE`
and `NOT LIKE` operations. There was also an [addition of `ilike` back in late
2021](https://github.com/apache/arrow-rs/commit/ee1d1644550d3c57443f5df76207d7a6503612b5),
which allows to performe `ILIKE` (case-insensitive `LIKE`) operations.
However, `nilike`, which is what `nlike` to `like` is, respectively (`NOT
ILIKE`) has been missing. It is a useful addition to perform similar `NOT`
operation with already supported `ILIKE`.
# What changes are included in this PR?
This PR adds `nilike` functions to `comparison` kernel that perform SQL
`left NOT ILIKE right` operation on arrays and scalars, as well as related
tests and benches.
# Are there any user-facing changes?
