file-content

A small library for reading file content/text data from disk, or anywhere else, into a String.

Supported Encodings

• UTF-8
• UTF-8-BOM
• UTF-16-BE
• UTF-16-LE
• or raw bytes

Usage

There are two main structs in this crate.

• file_content::File: A wrapper around a PathBuf and a file_content::FileContent.

  Use this struct for easily reading file content from disk that may be in any of the supported encodings.

• file_content::FileContent: An enum of the kind of content, either Encoded or Binary. If Encoded, the variant holds the encoding that content had, and a String representation of it in memory. If Binary, then a Vec<u8> of the raw data is held.

Example: read_file.rs reads a file from disk and prints the path, content type, and content:

use anyhow::anyhow;
use file_content::File;

fn main() -> anyhow::Result<()> {
    let file_path = std::env::args()
        .nth(1)
        .ok_or_else(|| anyhow!("Usage: read_file <file>"))?;

    let file: File = File::new_from_path(&file_path)?;

    println!("{:?}", file);

    let content_only: String = file_content::read_to_string(&file_path)?;

    println!("{content_only}");

    Ok(())
}
