Compilation Errors​

Error 1: Serde Attribute (src/events.rs:79)​

error: unknown serde variant attribute `skip_serializing_if`
  --> src/events.rs:79:13
   |
79 |     #[serde(skip_serializing_if = "is_false")]
   |             ^^^^^^^^^^^^^^^^^^^

Issue: Serde version mismatch or incorrect attribute usage

Fix needed: Check if using correct serde feature or update to skip_serializing_if = "Option::is_none" pattern

Error 2: Metrics Macro Syntax (src/observability.rs:26,31,36,41)​

error: expected labels, but comma not found
  --> src/observability.rs:26:55
   |
26 |         counter!("fs_monitor.events.received", "type" => event_type.to_string()).increment(1);
   |                                                       ^

Issue: Incorrect metrics macro syntax for labels

Current: counter!("metric.name", "label" => value)

Should be: counter!("metric.name", "label" = value) or check metrics crate version

Error 3: Missing Deserialize Derive (src/events.rs:17)​

error[E0277]: the trait bound `FileEventType: serde::Deserialize<'de>` is not satisfied
    --> src/events.rs:17:21
     |
  17 |     pub event_type: FileEventType,
     |                     ^^^^^^^^^^^^^ the trait `Deserialize<'_>` is not implemented for `FileEventType`

Issue: FileEventType enum missing Deserialize derive

Fix needed: Add #[derive(Deserialize)] to FileEventType enum definition

Error 4: Moved Value (src/monitor.rs:73)​

error[E0382]: use of moved value: `output_rx`
  --> src/monitor.rs:73:13
   |
34 |         let (output_tx, output_rx) = mpsc::channel(config.channel_buffer_size);
   |                         --------- move occurs because `output_rx` has type `tokio::sync::mpsc::Receiver<AuditEvent>`, which does not implement the `Copy` trait
...
68 |                 event_rx: output_rx,
   |                           --------- value moved here
...
73 |             output_rx,
   |             ^^^^^^^^^ value used here after move

Issue: output_rx used in two places

Fix needed: Clone the receiver or restructure to avoid dual ownership

Dependency Version Mismatch​

The code may have been written for different versions of:

  • serde (currently 1.0)
  • metrics (currently 0.21, but 0.22 is installed)

Option 1: Fix Code Errors​

Update the source code to match current crate versions:

  1. Fix serde attributes in src/events.rs
  2. Fix metrics macro syntax in src/observability.rs
  3. Add Deserialize derive to FileEventType
  4. Fix moved value issue in src/monitor.rs

Option 2: Update Dependencies​

Lock to specific versions that match the code:

[dependencies]
serde = "=1.0.228"
metrics = "=0.21.1"  # Match the exact version the code was written for

Option 3: Contact Original Author​

The code appears to have version mismatches. May need updated code from the original author.

Summary​

  • ✅ System dependencies: All installed
  • ✅ Rust toolchain: Working (cargo 1.90.0)
  • ❌ Source code: Has compilation errors
  • ❌ Build: Failed with 25 errors

The file-monitor cannot be built until source code errors are resolved.
