📝 Walkthrough

Walkthrough

Updates the Rust version requirement from 1.85.0 to 1.94.0 and refactors a condition check in the pinned consistency validation logic to use chained conditional expressions instead of nested if statements. Behavior remains unchanged.

Changes

Cohort / File(s)	Summary
Version Requirement Update Cargo.toml	Bumps minimum Rust version from 1.85.0 to 1.94.0 in package metadata.
Condition Refactoring src/checks.rs	Simplifies nested if conditions into a single chained if-let expression for the check_pinned_consistency logic, maintaining equivalent control flow.

Poem

🐰 Hopping through the code with glee,
Rust grows newer—1.94, you see!
Nested ifs collapse with care,
Chained conditions, sleek and fair,
The warren's updated, swift and spry!

Which Rust release stabilized let_chains for Edition 2024, and in which Rust release did Rust 2024 itself become stable?

💡 Result:

• let_chains (the #![feature(let_chains)] gate) was stabilized for the Rust 2024 Edition in Rust 1.88.0 (2025-06-26). [1]
• Rust 2024 (Edition 2024) itself became stable in Rust 1.85.0 (2025-02-20). [2][1]

Avoid raising the MSRV higher than this refactor needs.

Rust 2024 Edition became stable in Rust 1.85.0 (2025-02-20), and let_chains was stabilized for Edition 2024 in Rust 1.88.0 (2025-06-26). The guard refactor in src/checks.rs using chained let conditions requires only 1.88.0, not 1.94.0. Unless there is a separate requirement elsewhere in this branch that specifically needs 1.94.0, lower the MSRV to 1.88.0; otherwise, users on 1.88–1.93 unnecessarily lose compatibility.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	rust-version = "1.94.0"
