Function async_extract_metadata_from_file

pub async fn async_extract_metadata_from_file(
    file_path: &str,
) -> Result<(HashMap<String, String>, Vec<String>, MetaTagGroups), MetadataError>

Asynchronously reads a file and extracts metadata from its content.

This function reads the content of a file asynchronously and then extracts metadata, generates keywords, and prepares meta tag groups.

Arguments

• file_path - A string slice representing the path to the file.

Returns

Returns a Result containing a tuple with:

• HashMap<String, String>: Extracted metadata
• Vec<String>: A list of keywords
• MetaTagGroups: A structure containing various meta tags

Errors

This function will return a MetadataError if:

• File reading fails (e.g., file not found, permission denied)
• Metadata extraction or processing fails

Examples

use metadata_gen::utils::async_extract_metadata_from_file;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let (metadata, keywords, meta_tags) = async_extract_metadata_from_file("path/to/file.md").await?;
    println!("Metadata: {:?}", metadata);
    println!("Keywords: {:?}", keywords);
    println!("Meta tags: {}", meta_tags);
    Ok(())
}

Security

This function reads files from the file system. Ensure that the file_path is properly sanitized and validated to prevent potential security issues like path traversal attacks.
