Agent Quick Fix

Repair against the current Rust 2024 contract, then keep the change narrow and source-backed.

Product: Rust 2024
Current-contract area: `Future` prelude import creates an ambiguous local name
Likely root cause: An unchanged module gets a name-resolution ambiguity only in edition 2024.
Repair direction: Verifier checks idiomatic migration while preserving cross-version intent where required.

Symptom

An unchanged module gets a name-resolution ambiguity only in edition 2024.

Why This Happens

Source may compile under an older edition/toolchain; current edition migration rules and tool metadata are external to the repo's immediate error context.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
