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
impl ModuleMetadata
sourcepub fn split(
&mut self
) -> (&mut CompileModuleInfo, ModuleMetadataSymbolRegistry)
pub fn split( &mut self ) -> (&mut CompileModuleInfo, ModuleMetadataSymbolRegistry)
Get mutable ref to compile info and a copy of the registry
sourcepub fn get_symbol_registry(&self) -> ModuleMetadataSymbolRegistry
pub fn get_symbol_registry(&self) -> ModuleMetadataSymbolRegistry
Returns symbol registry.
sourcepub fn serialize(&self) -> Result<Vec<u8>, SerializeError>
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)
sourcepub unsafe fn deserialize(
metadata_slice: &[u8]
) -> Result<Self, DeserializeError>
pub unsafe 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)
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
).
sourcepub fn deserialize_checked(
metadata_slice: &[u8]
) -> Result<Self, DeserializeError>
pub fn deserialize_checked( 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)
sourcepub fn deserialize_from_archive(
archived: &ArchivedModuleMetadata
) -> Result<Self, DeserializeError>
pub fn deserialize_from_archive( archived: &ArchivedModuleMetadata ) -> Result<Self, DeserializeError>
Deserialize a compilation module from an archive
