详细描述

One content-digest implementation usable for snapshot sealing and verification.

备注

Implementations must be pure and deterministic: the same input must always produce the same id, or a snapshot could never be verified after a restart.

构造及析构函数说明

~ISnapshotContentHasher()

virtual eve::ISnapshotContentHasher::~ISnapshotContentHasher ( )

virtualdefault

Releases ISnapshotContentHasher resources.

成员函数说明

digestKind()

virtual ContentDigestKind eve::ISnapshotContentHasher::digestKind ( ) const

pure virtualnoexcept

What this digest guarantees.

hash()

virtual Result< ContentId > eve::ISnapshotContentHasher::hash ( std::string_view  canonicalInput ) const

pure virtual

Digest one canonical snapshot input.

参数

canonicalInput

Canonical JSON assembled by common/Snapshot.*.

返回

A 128-bit content id, or a structured failure.

id()

virtual std::string_view eve::ISnapshotContentHasher::id ( ) const

pure virtualnoexcept

Stable algorithm id, persisted or logged next to the data it hashed.
