Struct FileDiscovery 

pub struct FileDiscovery { /* private fields */ }

File discovery engine with glob pattern support.

Discovers files matching specified patterns with configurable filtering and traversal options.

Implementations

impl FileDiscovery

pub fn new(patterns: Vec<String>, config: DiscoveryConfig) -> Self

Create a new file discovery instance.

Arguments

• patterns - List of file patterns (glob patterns or explicit paths)
• config - Discovery configuration

Examples

use hedl_cli::file_discovery::{FileDiscovery, DiscoveryConfig};

let discovery = FileDiscovery::new(
    vec!["*.hedl".to_string(), "data/*.hedl".to_string()],
    DiscoveryConfig::default()
);

pub fn validate_patterns(&self) -> Result<(), CliError>

Validate all patterns before discovery.

Checks that patterns are valid glob expressions.

Returns

• Ok(()) - All patterns are valid
• Err(CliError::GlobPattern) - Invalid pattern found

Examples

use hedl_cli::file_discovery::{FileDiscovery, DiscoveryConfig};

let discovery = FileDiscovery::new(
    vec!["*.hedl".to_string()],
    DiscoveryConfig::default()
);
assert!(discovery.validate_patterns().is_ok());

pub fn discover(&self) -> Result<Vec<PathBuf>, CliError>

Discover all files matching the patterns.

Expands glob patterns and applies configured filters.

Returns

• Ok(Vec<PathBuf>) - List of discovered file paths
• Err(CliError) - On pattern errors, I/O failures, or no matches

Errors

Returns error if:

• Pattern is invalid
• No files match any pattern
• Directory traversal fails

Examples

use hedl_cli::file_discovery::{FileDiscovery, DiscoveryConfig};

let discovery = FileDiscovery::new(
    vec!["tests/*.hedl".to_string()],
    DiscoveryConfig::default()
);
let files = discovery.discover()?;
println!("Found {} files", files.len());
