ADR-001: Rust as Primary Language

Status

Accepted

Context

Wisdoverse Nexus is an AI-Native team communication platform that requires:

• High concurrency (thousands of WebSocket connections)
• Low latency (real-time messaging)
• Memory safety (handling user data)
• Performance (AI provider integration)

Options considered:

• Go: Good concurrency, garbage collection pauses
• Node.js: Great ecosystem, single-threaded limitations
• Rust: Zero-cost abstractions, memory safety, async support

Decision

Use Rust as the primary backend language.

Consequences

Positive

• Memory safety without garbage collection
• Excellent async/await support with Tokio
• Type safety reduces runtime errors
• High performance (no GC pauses)
• Growing ecosystem for web services (Axum, Tower)

Negative

• Steeper learning curve
• Slower development velocity initially
• Smaller talent pool compared to Go/Node.js

Mitigation

• Comprehensive documentation
• Clear code patterns
• Code review process
