Struct gear_core::code::Code

pub struct Code { /* private fields */ }

Contains instrumented binary code of a program and initial memory size from memory import.

Implementations

impl Code

pub fn try_new<R, GetRulesFn>( raw_code: Vec<u8>, version: u32, get_gas_rules: GetRulesFn, stack_height: Option<u32> ) -> Result<Self, CodeError>where R: Rules, GetRulesFn: FnMut(&Module) -> R,

Create the code by checking and instrumenting original_code.

pub fn new_raw( original_code: Vec<u8>, version: u32, module: Option<Module>, instrument_with_const_rules: bool, check_entries: bool ) -> Result<Self, CodeError>

Create the code without instrumentation or instrumented with ConstantCostRules. There is also no check for static memory pages.

pub fn new_raw_with_rules<R, GetRulesFn>( original_code: Vec<u8>, version: u32, check_entries: bool, get_gas_rules: GetRulesFn ) -> Result<Self, CodeError>where R: Rules, GetRulesFn: FnMut(&Module) -> R,

Create the code with instrumentation, but without checks. There is also no check for static memory pages.

pub fn raw_code(&self) -> &[u8]

Returns the original code.

pub fn code(&self) -> &[u8]

Returns reference to the instrumented binary code.

pub fn exports(&self) -> &BTreeSet<DispatchKind>

Returns wasm module exports.

pub fn instruction_weights_version(&self) -> u32

Returns instruction weights version.

pub fn static_pages(&self) -> WasmPage

Returns initial memory size from memory import.

pub fn into_parts(self) -> (InstrumentedCode, Vec<u8>)

Consumes this instance and returns the instrumented and raw binary codes.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Code

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decode for Code

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for Code

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq<Code> for Code

fn eq(&self, other: &Code) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for Code

type Identity = Code

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
