Make Rust Faster Than C: workplan

Draft Work plan

Milestone 1: State machine codegen

• Merge RFC 3720 (improved state machines)
• Implement RFC 3720 in the rust compiler
• Identify popular rust projects that benefit from RFC 3720

Effort: 4 person-weeks

Milestone 2: Identify performance bottlenecks

• Research the performance challenges in key projects (e.g. Servo, RfL, serde, NVMe driver, c2rust, rav1d, ripgrep)
• Talk to expert rust project members to document direction and bottlenecks of improving the backend
• Find and document examples in key projects where the backend optimizes poorly

Effort: 6 person-weeks

Draft Milestone 3: Create plan

We're in the process of gathering input to make this milestone more specific. This includes understanding prior work and ideas, and balancing expected effort and expected reward.

• Create a coordinated plan
• Get commitment of team members, contributers and backers
• Secure funding for execution

Effort estimate: 6-12 person-weeks

Draft Milestone 4: Execute the plan

• Execute the plan
• Be faster than C

Effort estimate: 1-2 person-years
