Expand description

Serializable struct that represents the compiled metadata.

Fields§

§compile_info: CompileModuleInfo

Compile info

§prefix: String

Prefix for function etc symbols

§data_initializers: Box<[OwnedDataInitializer]>

Data initializers

§function_body_lengths: PrimaryMap<LocalFunctionIndex, u64>

The function body lengths (used to find function by address)

§cpu_features: u64

CPU features used (See CpuFeature)

Implementations§

source§

impl ModuleMetadata

source

pub fn split( &mut self ) -> (&mut CompileModuleInfo, ModuleMetadataSymbolRegistry)

Get mutable ref to compile info and a copy of the registry

source

pub fn get_symbol_registry(&self) -> ModuleMetadataSymbolRegistry

Returns symbol registry.

source

pub fn serialize(&self) -> Result<Vec<u8>, SerializeError>

Serialize a Module into bytes The bytes will have the following format: RKYV serialization (any length) + POS (8 bytes)

source

pub unsafe fn deserialize_unchecked( metadata_slice: &[u8] ) -> Result<Self, DeserializeError>

Deserialize a Module from a slice. The slice must have the following format: RKYV serialization (any length) + POS (8 bytes)

Safety

This method is unsafe since it deserializes data directly from memory. Right now we are not doing any extra work for validation, but rkyv has an option to do bytecheck on the serialized data before serializing (via rkyv::check_archived_value).

source

pub fn deserialize(metadata_slice: &[u8]) -> Result<Self, DeserializeError>

Deserialize a Module from a slice. The slice must have the following format: RKYV serialization (any length) + POS (8 bytes)

source

pub fn deserialize_from_archive( archived: &ArchivedModuleMetadata ) -> Result<Self, DeserializeError>

Deserialize a compilation module from an archive
