snarkOS: Compilation Failure in snarkOS-node-consensus v2.2.7 due to Deprecated Methods and Type Mismatch

🐛 Bug Report

Description

During the compilation of snarkOS-node-consensus v2.2.7, multiple warnings and an error were encountered related to deprecated methods and mismatched types.

Severity

The issue seems to block the compilation process, indicating a critical severity level as it halts further development or usage of the software until resolved.

Affected

This affects the snarkOS-node-consensus module, particularly the compilation process which is critical for development and deployment.

Steps to Reproduce

1. Compile snarkOS-node-consensus v2.2.7 using Rust.
2. Observe the warnings about deprecated indexmap::IndexMap::remove methods.
3. Encounter the error E0308: mismatched types in node/rest/src/lib.rs at line 115:54.

Error Messages and Stack Traces

• Warnings for deprecated indexmap::IndexMap::remove method suggest using swap_remove for explicit behavior.
• Compilation error E0308 in node/rest/src/lib.rs indicates an expected Body type but found a String type instead.

Expected Behavior

The compilation process should complete without errors or warnings, allowing the software to build successfully.
