IntegrityChecker

Struct IntegrityChecker 

Source
pub struct IntegrityChecker {
    pub metadata: BackupMetadata,
}
Expand description

整合性検証エンジン

バックアップ時のハッシュ計算と保存を担当します。

§使用例

use backup_suite::core::integrity::IntegrityChecker;
use std::path::PathBuf;

let mut checker = IntegrityChecker::new();

// ファイルハッシュ計算と追加
let file = PathBuf::from("test.txt");
let hash = checker.compute_hash(&file).unwrap();
checker.add_file_hash(file, hash);

// メタデータ保存
let backup_dir = PathBuf::from("/backup/backup_20250107_120000");
checker.save_metadata(&backup_dir).unwrap();

Implementations§

Source§

impl IntegrityChecker

Source

pub fn new() -> Self

新しいIntegrityCheckerを作成

§戻り値

空のメタデータを持つ IntegrityChecker インスタンス

§使用例
use backup_suite::core::integrity::IntegrityChecker;

let checker = IntegrityChecker::new();
Source

pub fn compute_hash(&self, file_path: &Path) -> Result<String>

ファイルのSHA-256ハッシュを計算

§引数
  • file_path - ハッシュ計算対象のファイルパス
§戻り値

成功時は16進数文字列形式のSHA-256ハッシュ、失敗時はエラー

§Errors

以下の場合にエラーを返します:

  • ファイルのオープンに失敗した場合
  • ファイルの読み込みに失敗した場合
§使用例
use backup_suite::core::integrity::IntegrityChecker;
use std::path::PathBuf;

let checker = IntegrityChecker::new();
let hash = checker.compute_hash(&PathBuf::from("test.txt")).unwrap();
println!("SHA-256: {}", hash);
Source

pub fn add_file_hash(&mut self, relative_path: PathBuf, hash: String)

ファイルハッシュをメタデータに追加

§引数
  • relative_path - バックアップ内の相対パス
  • hash - SHA-256ハッシュ(16進数文字列)
§使用例
use backup_suite::core::integrity::IntegrityChecker;
use std::path::PathBuf;

let mut checker = IntegrityChecker::new();
checker.add_file_hash(PathBuf::from("test.txt"), "abc123...".to_string());
Source

pub fn save_metadata(&self, backup_dir: &Path) -> Result<()>

メタデータをバックアップディレクトリに保存

§引数
  • backup_dir - バックアップディレクトリのパス
§戻り値

成功時は Ok(())、失敗時はエラー

§Errors

以下の場合にエラーを返します:

  • メタデータの保存に失敗した場合
§使用例
use backup_suite::core::integrity::IntegrityChecker;
use std::path::PathBuf;

let mut checker = IntegrityChecker::new();
checker.add_file_hash(PathBuf::from("test.txt"), "abc123...".to_string());
checker.save_metadata(&PathBuf::from("/backup/backup_20250107_120000")).unwrap();
Source

pub fn file_count(&self) -> usize

保存予定のファイル数を取得

§戻り値

§使用例
use backup_suite::core::integrity::IntegrityChecker;
use std::path::PathBuf;

let mut checker = IntegrityChecker::new();
checker.add_file_hash(PathBuf::from("test.txt"), "abc123...".to_string());
assert_eq!(checker.file_count(), 1);
