Public 成员函数

 AtomicAssetPackageStore (BeforeReplace beforeReplace={})
 Construct a publisher, optionally with a failure-injection/policy gate.
 
Result< PackagePublishReceipt > publishEva (const std::filesystem::path &destination, const EvaManifest &manifest, std::vector< EvaArchiveEntry > entries, const EvaArchiveLimits &limits={})
 Build, reopen-verify and atomically publish one .eva source archive.
 
Result< PackagePublishReceipt > publishEvpack (const std::filesystem::path &destination, std::span< const std::uint8_t > bytes, const EvpackLimits &limits={}, const EvpackTrust &trust={})
 Reopen-verify and atomically publish already cooked .evpack bytes.
 

详细描述

Filesystem publisher whose failed prepare/verify leaves the destination unchanged.

备注
The optional gate is invoked after reopening the temporary file and before replacement, without a store lock. It must not retain references to its path arguments.

成员类型定义说明

◆ BeforeReplace

using eve::asset::AtomicAssetPackageStore::BeforeReplace = std::function<PackagePublishGateDecision( const std::filesystem::path& temporary, const std::filesystem::path& destination)>

在文件 AssetPackageStore.h 第 41 行定义.

构造及析构函数说明

◆ AtomicAssetPackageStore()

eve::asset::AtomicAssetPackageStore::AtomicAssetPackageStore ( BeforeReplace  beforeReplace = {})
explicit

Construct a publisher, optionally with a failure-injection/policy gate.

在文件 AssetPackageStore.cpp 第 131 行定义.

成员函数说明

◆ publishEva()

Result< PackagePublishReceipt > eve::asset::AtomicAssetPackageStore::publishEva ( const std::filesystem::path &  destination,
const EvaManifest &  manifest,
std::vector< EvaArchiveEntry >  entries,
const EvaArchiveLimits &  limits = {} 
)

Build, reopen-verify and atomically publish one .eva source archive.

返回
Receipt after replacement, or a diagnostic with the old destination intact. @thread Concurrent calls on this instance are safe. @reentrancy The gate may call unrelated services but must not recursively publish to this store.

在文件 AssetPackageStore.cpp 第 134 行定义.

引用了 eve::asset::buildEvaArchive(), eve::Cancelled, entries, eve::Diagnostic::error(), eve::Failed, eve::Result< T >::failure(), eve::InvalidArgument, limits, eve::asset::EvaManifest::packageId, eve::asset::parseEvaArchive(), eve::asset::Reject , 以及 eve::Result< T >::success().

◆ publishEvpack()

Result< PackagePublishReceipt > eve::asset::AtomicAssetPackageStore::publishEvpack ( const std::filesystem::path &  destination,
std::span< const std::uint8_t >  bytes,
const EvpackLimits &  limits = {},
const EvpackTrust &  trust = {} 
)

Reopen-verify and atomically publish already cooked .evpack bytes.

返回
Receipt after replacement, or a diagnostic with the old destination intact. @thread Concurrent calls on this instance are safe. @reentrancy The gate may call unrelated services but must not recursively publish to this store.

在文件 AssetPackageStore.cpp 第 167 行定义.

引用了 bytes, eve::Cancelled, eve::Diagnostic::error(), eve::Failed, eve::Result< T >::failure(), eve::InvalidArgument, limits, packageId, eve::asset::parseEvpack(), eve::asset::Reject , 以及 eve::Result< T >::success().
