cargo-deduplicate-warnings

This crate is a binary which deduplicates warning messages in the json output of cargo.

Normally, cargo does this for you when using its normal output. However, when you have other tools that consume cargo's json output (e.g. clippy-sarif) then the duplicate warnings show up downstream. This crate allows you to avoid the issue by stripping them out.

Usage

cargo clippy --message-format json | cargo deduplicate-warnings | ...
