Struct Otw 

pub struct Otw { /* private fields */ }

Generic type signaling a one-time-witness type argument.

None of address, module and name are known at compile time, only that there are no type parameters

This is useful when calling associated methods on a move type that don’t depend on the specific type argument.

Examples

use af_move_type::{MoveStruct, MoveType, otw::Otw};
use serde::{Deserialize, Serialize};

#[derive(MoveStruct, Clone, Debug, Default, Deserialize, Serialize, PartialEq, Eq, Hash)]
#[move_(address = "0x2", module = balance)]
pub struct Balance<T: MoveType> {
    value: u64,
    _otw: std::marker::PhantomData<T>,
}

// for compilation purposes
impl<T: MoveType> std::fmt::Display for Balance<T> {
fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
    todo!()
}
}

let address = "0x2".parse().unwrap();
let module = "sui".parse().unwrap();
let name = "SUI".parse().unwrap();
let otw = Otw::type_(address, module, name);
let usdc_type = Balance::<Otw>::type_(otw);

Trait Implementations

impl Clone for Otw

fn clone(&self) -> Otw

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Otw

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

Formats the value using the given formatter.

impl Default for Otw

fn default() -> Otw

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Otw

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Otw

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

Formats the value using the given formatter.

impl Hash for Otw

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MoveStruct for Otw

type StructTag = OtwTypeTag

impl MoveType for Otw

type TypeTag = OtwTypeTag

fn from_bcs(bytes: &[u8]) -> Result<Self>

Deserialize the contents of the Move type from BCS bytes.

fn into_bcs(self) -> Result<Vec<u8>>

Consuming version of to_bcs.

fn to_bcs(&self) -> Result<Vec<u8>>

Serialize the contents of the Move type to BCS bytes.

fn into_json(self) -> Value

Consuming version of to_json.

fn to_json(&self) -> Value

Serialize the contents of the Move type to JSON.

impl PartialEq for Otw

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Otw

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StaticTypeParams for Otw

fn type_params() -> Vec<TypeTag>

impl Eq for Otw

impl StructuralPartialEq for Otw
