Module bevy::asset::processor

Structs

• AssetProcessor
  A “background” asset processor that reads asset values from a source AssetSource (which corresponds to an AssetReader / AssetWriter pair), processes them in some way, and writes them to a destination AssetSource.
• AssetProcessorData
• LoadAndSave
  A flexible Process implementation that loads the source Asset using the L AssetLoader, then saves that L asset using the S AssetSaver.
• LoadAndSaveSettings
  Settings for the LoadAndSave Process::Settings implementation.
• LoadTransformAndSave
  A flexible Process implementation that loads the source Asset using the L AssetLoader, then transforms the L asset into an S AssetSaver asset using the T AssetTransformer, and lastly saves the asset using the S AssetSaver.
• LoadTransformAndSaveSettings
  Settings for the LoadTransformAndSave Process::Settings implementation.
• ProcessContext
  Provides scoped data access to the AssetProcessor. This must only expose processor data that is represented in the asset’s hash.
• ProcessorAssetInfos
  The “current” in memory view of the asset space. This is “eventually consistent”. It does not directly represent the state of assets in storage, but rather a valid historical view that will gradually become more consistent as events are processed.
• ProcessorTransactionLog
  A “write ahead” logger that helps ensure asset importing is transactional. Prior to processing an asset, we write to the log to indicate it has started After processing an asset, we write to the log to indicate it has finished. On startup, the log can be read to determine if any transactions were incomplete.
• WriteLogError
  An error that occurs when writing to the ProcessorTransactionLog fails.

Enums

• InitializeError
  An error that occurs when initializing the AssetProcessor.
• LogEntryError
  An error that occurs when validating individual ProcessorTransactionLog entries.
• ProcessError
  An error that is encountered during Process::process.
• ProcessResult
  The (successful) result of processing an asset
• ProcessStatus
  The final status of processing an asset
• ProcessorState
  The current state of the AssetProcessor.
• ReadLogError
  An error that occurs when reading from the ProcessorTransactionLog fails.
• ValidateLogError
  An error that occurs when validating the ProcessorTransactionLog fails.

Traits

• ErasedProcessor
  A type-erased variant of Process that enables interacting with processor implementations without knowing their type.
• Process
  Asset “processor” logic that reads input asset bytes (stored on ProcessContext), processes the value in some way, and then writes the final processed bytes with Writer. The resulting bytes must be loadable with the given Process::OutputLoader.
