Code Review
This pull request introduces a good set of code quality improvements and optimizations, adhering to Rust best practices. The changes, such as implementing the Default trait, using .clamp() for conciseness, and removing unnecessary clones, enhance code readability and maintainability. However, I've identified a couple of areas for improvement. The OPTIMIZATION_CHANGELOG.md contains values that are inconsistent with the actual code changes, which could be misleading. Additionally, the number of scan retries is silently clamped, which might confuse users who expect their configuration to be fully respected. My review includes specific suggestions to address these points.

| for attempt in 1..=tries { | ||

This line has two issues that could lead to unexpected behavior for users:
-
Silent Clamping: The number of attempts is silently clamped to a maximum of 3 with
.min(3). A user setting--max-retries=5would unknowingly only get 3 attempts. This unexpected behavior should be avoided. It's better to trust the user's configuration or log a warning if the value is adjusted. -
"Retries" vs. "Attempts": The CLI flag is named
--max-retries, which usually means the number of extra attempts after the first one. However, this code uses it as the total number of attempts (for attempt in 1..=max_tries). This can be confusing.
I recommend removing the upper clamp. To address the naming confusion, you should also consider renaming the --max-retries flag to --attempts in src/main.rs to make its purpose clear.

The optimization values documented in this changelog for batch size and adaptive batch size are inconsistent with the actual changes implemented in src/scanner/engine.rs. This can be misleading for anyone reading the changelog to understand the performance tuning.
For example:
- Changelog:
AVERAGE_BATCH_SIZEis changed to5000. - Code:
AVERAGE_BATCH_SIZEis changed to2000insrc/scanner/engine.rs. - Changelog: Adaptive batch size increase is capped at
10000. - Code: The cap is
4000insrc/scanner/engine.rs.
Please update this changelog to reflect the actual values in the code to ensure documentation accuracy.

Division-by-zero risks in batch_size() when threads == 0
Two branches divide by self.threads without guarding, which can panic before validate() runs.
Apply guards:
- let base_batch = if self.ports.len() > 60000 {
+ let base_batch = if self.ports.len() > 60000 {
// Full port range - moderate batches for stability
- let optimal = self.ports.len() / (self.threads / 2).max(1);
+ let optimal = self.ports.len() / (self.threads / 2).max(1);
optimal.clamp(1000, 3000)
} else if self.ports.len() > 10000 {
// Medium ranges - balanced approach
- std::cmp::max(300, self.ports.len() / self.threads)
+ std::cmp::max(300, self.ports.len() / self.threads.max(1))
} else {
// Small ranges - smaller batches
std::cmp::max(
200, // Safe minimum batch size
std::cmp::min(
- (self.rate_limit as usize) / (self.threads * cpu_cores),

In src/config.rs around lines 151 to 172, the batch_size() logic divides by
self.threads in multiple branches which can cause a division-by-zero panic if
threads == 0; change the code to guard against zero threads by normalizing
threads to at least 1 up front (e.g. let threads = self.threads.max(1)) and then
use that local threads variable in all subsequent calculations, replacing
occurrences of self.threads so no division-by-zero can occur.
