Trait Implementations

impl Clone for OpcodeCosts

fn clone(&self) -> OpcodeCosts

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for OpcodeCosts

impl DataSize for OpcodeCosts

const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for OpcodeCosts

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

Formats the value using the given formatter.

impl Default for OpcodeCosts

fn default() -> Self

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for OpcodeCosts

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Eq for OpcodeCosts

impl FromBytes for OpcodeCosts

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

pub fn from_vec(
    bytes: Vec<u8, Global>
) -> Result<(Self, Vec<u8, Global>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq<OpcodeCosts> for OpcodeCosts

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

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

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

This method tests for !=.

impl Serialize for OpcodeCosts

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl StructuralEq for OpcodeCosts

impl StructuralPartialEq for OpcodeCosts

impl ToBytes for OpcodeCosts

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

pub fn into_bytes(self) -> Result<Vec<u8, Global>, Error>

Consumes self and serializes to a Vec<u8>.
