Crate pas_external 

pas-external

Ppoppo Accounts System (PAS) client for Rust.

• OAuth2 PKCE authentication flow
• PASETO v4.public token verification
• Axum middleware for plug-and-play auth routes

Usage

[dependencies]
pas-external = { version = "0.1", features = ["axum"] }

For downstream consumer integration tests, enable test-support to access MemoryPasAuth (deterministic in-memory PAS substitute, FIFO-scripted):

[dev-dependencies]
pas-external = { version = "0.1", features = ["axum", "test-support"] }

Pre-1.0: minor bumps (0.2, 0.3) may include breaking changes per SemVer §11. Versions 1.0.1 – 5.0.0 were yanked from crates.io on 2026-04-30 as part of a pre-1.0 version reset; 0.1.0 is equivalent in scope to the (yanked) 5.0.0 development line. See CHANGELOG.md for the design history and 0context/STANDARDS_SESSION_LIVENESS.md for the consumer-facing contract.
