Implementations

impl SchemaSnapshot

pub fn read_from(path: &Path) -> Result<SchemaSnapshot, Error>

파일에서 로드

pub fn from_slice(bytes: &[u8]) -> Result<SchemaSnapshot, Error>

Parse a snapshot from raw JSON bytes (e.g. a decompressed embedded blob).

pub fn to_json(&self) -> Result<String, Error>

Serialize to the pretty JSON format used by snapshot files.

pub fn write_to(&self, path: &Path) -> Result<(), Error>

파일로 저장 (pretty JSON — 리뷰 가능한 diff)

pub fn table(&self, name: &str) -> Option<&TableSnapshot>

테이블 조회

pub fn canonical_string(&self) -> String

정준 문자열 — 해시 입력. 테이블은 이름순 정렬, 컬럼은 선언 순서 유지. 각 가변 필드는 길이 접두사({len}:{값})로 인코딩해 필드 경계 충돌을 원천 차단한다 (L-14).

pub fn hash(&self) -> u64

FNV-1a 64 해시 — 스테일 감지용 (명세 §7.4). 암호학적 강도 불필요.
