Struct ParsedModule

pub struct ParsedModule {
    pub module: Module,
    pub proto_version: u32,
    pub cost_inputs: VersionedContractCodeCostInputs,
}

A ParsedModule contains the parsed wasmi::Module for a given Wasm blob, as well as a protocol number and set of [ContractCodeCostInputs] extracted from the module when it was parsed.

Fields

module: Module

proto_version: u32

cost_inputs: VersionedContractCodeCostInputs

Implementations

impl ParsedModule

pub fn new( host: &Host, engine: &Engine, wasm: &[u8], cost_inputs: VersionedContractCodeCostInputs, ) -> Result<Rc<Self>, HostError>

pub fn with_import_symbols<T>( &self, host: &Host, callback: impl FnOnce(&BTreeSet<(&str, &str)>) -> Result<T, HostError>, ) -> Result<T, HostError>

pub fn make_linker(&self, host: &Host) -> Result<Linker<Host>, HostError>

pub fn new_with_isolated_engine( host: &Host, wasm: &[u8], cost_inputs: VersionedContractCodeCostInputs, ) -> Result<Rc<Self>, HostError>

pub fn custom_section(&self, name: impl AsRef<str>) -> Option<&[u8]>

Returns the raw bytes content of a named custom section from the Wasm module loaded into the Vm, or None if no such custom section exists.

pub fn extract_refined_contract_cost_inputs( host: &Host, wasm: &[u8], ) -> Result<ContractCodeCostInputs, HostError>
