Struct Scanner

pub struct Scanner { /* private fields */ }

Directory scanner for detecting development projects.

The Scanner struct encapsulates the logic for traversing directory trees and identifying development projects (Rust and Node.js) along with their build artifacts. It supports configurable filtering and parallel processing for efficient scanning of large directory structures.

Implementations

impl Scanner

pub fn new(scan_options: ScanOptions, project_filter: ProjectFilter) -> Self

Create a new scanner with the specified options.

Arguments

• scan_options - Configuration for scanning behavior (threads, verbosity, etc.)
• project_filter - Filter to restrict scanning to specific project types

Returns

A new Scanner instance configured with the provided options.

Examples

let scan_options = ScanOptions {
    verbose: true,
    threads: 4,
    skip: vec![],
};

let scanner = Scanner::new(scan_options, ProjectFilter::All);

pub fn scan_directory(&self, root: &Path) -> Vec<Project>

Scan a directory tree for development projects.

This method performs a recursive scan of the specified directory to find development projects. It operates in two phases:

1. Directory traversal to identify potential projects
2. Parallel size calculation for build directories

Arguments

• root - The root directory to start scanning from

Returns

A vector of Project instances representing all detected projects with non-zero build directory sizes.

Panics

This method may panic if the progress bar template string is invalid, though this should not occur under normal circumstances as the template is hardcoded and valid.

Examples

let projects = scanner.scan_directory(Path::new("/path/to/projects"));
println!("Found {} projects", projects.len());

Performance

This method uses parallel processing for both directory traversal and size calculation to maximize performance on systems with multiple cores and fast storage.
