Struct ContentVerifier 

pub struct ContentVerifier;

Verifies file integrity through content comparison and hashing

Implementations

impl ContentVerifier

pub fn new() -> Self

Creates a new ContentVerifier instance

pub fn compute_hash(content: &str) -> String

Computes SHA-256 hash of content

Arguments

• content - The content to hash

Returns

Hexadecimal string representation of the SHA-256 hash

pub async fn verify_write( &self, path: &Path, expected: &str, ) -> Result<(), FileError>

Verifies that written content matches source byte-for-byte

Arguments

• path - Path to the written file
• expected - Expected content

Returns

Ok(()) if verification succeeds, error otherwise

pub async fn verify_backup( &self, backup_path: &Path, stored_hash: &str, ) -> Result<(), FileError>

Verifies backup integrity by comparing stored hash with computed hash

Arguments

• backup_path - Path to the backup file
• stored_hash - Previously stored hash to compare against

Returns

Ok(()) if hashes match (no corruption), error if mismatch or read fails
