# cargo-deny configuration
# Docs: https://embarkstudios.github.io/cargo-deny/
# Schema: cargo-deny 0.16+ (v2 action)
#
# Policy summary:
#   advisories - deny vulnerabilities; warn on unmaintained/unsound for all deps
#   licenses   - warn on unapproved licenses (not fail, to avoid blocking on new transitive deps)
#   bans       - warn on duplicate major versions
#   sources    - crates.io only (no git deps in production crates)

[advisories]
# vulnerability is always an error in cargo-deny v2 (no config needed).

# "all"        - report for all dependencies (direct + transitive)
# "workspace"  - only report for workspace members
# "transitive" - only report for transitive deps
# "none"       - suppress entirely
unmaintained = "all"
unsound = "all"
yanked = "warn"

# Add reviewed advisory IDs here to suppress specific known false-positives:
# ignore = ["RUSTSEC-2021-0001"]

[licenses]
# cargo-deny 0.16+: only `allow` list is supported (no default/unlicensed/copyleft fields).
# Any crate whose license is not in this list will be an error.
# Add licenses to this list as needed when new transitive deps are introduced.
