枚举类型说明

PixelChunkArchiveCodec

enum class eve::pixelworld_streaming::PixelChunkArchiveCodec : std::uint8_t

strong

Stable physical codec for one independently stored PixelWorld Chunk.

枚举值
None
Zstd

在文件 PixelWorldStreaming.h 第 16 行定义.

函数说明

archiveChunkBatch()

EVENGINE_API_PLATFORM eve::Result< eve::SnapshotEnvelope > eve::pixelworld_streaming::archiveChunkBatch	(	const eve::pixelworld::PixelChunkBatch &	batch,
		eve::PersistentId	instanceId,
		PixelChunkArchiveCodec	codec,
		const eve::SnapshotHashProvider &	hashProvider
	)

Encode one authoritative batch as pixelworld:chunk-batch SnapshotEnvelope version 3.

参数

batch	Canonical owning batch to persist.
instanceId	Stable world/save identity.
codec	Per-present-Chunk physical compression codec.
hashProvider	Injected digest used by the envelope and every decoded Chunk.

返回

Integrity-sealed archive with independently compressed Chunk records.

decodeChunkBatchArchive()

EVENGINE_API_PLATFORM eve::Result< eve::pixelworld::PixelChunkBatch > eve::pixelworld_streaming::decodeChunkBatchArchive	(	const eve::SnapshotEnvelope &	snapshot,
		const eve::SnapshotHashProvider &	hashProvider
	)

Verify and decode a version 1, 2 or 3 Chunk-batch archive into an owning candidate.

备注

Decoding is bounded and has no world side effects. Version 1 migrates with sourceLastEditSequence == 0; versions 1 and 2 migrate with fullResync == false. Bad envelope/Chunk hashes fail before any authority write.
