Function read_file_to_string 

pub fn read_file_to_string(path: &Path, max_size: Option<u64>) -> Result<String>

Reads a file’s entire contents into a String with ADR 0004 security checks.

Performs the following validations before reading:

1. File existence: checks fs::metadata() before opening
2. File size: rejects files exceeding max_size (default 100 MB)
3. UTF-8 encoding: on UTF-8 failure, falls back to lossy conversion with a warning

Arguments

• path - Path to the file to read
• max_size - Maximum allowed file size in bytes (defaults to MAX_MANIFEST_SIZE)

Returns

• Ok(String) - File contents as UTF-8 string (lossy if non-UTF-8 bytes found)
• Err - File doesn’t exist, is too large, or cannot be read

Examples

use std::path::Path;
use provenant::parsers::utils::read_file_to_string;

let content = read_file_to_string(Path::new("path/to/file.txt"), None)?;
