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.

Use this when you want to instantiate a datatype like Balance<phantom T> that expects its type argument to be a Move one-time-witness.

Examples

use moverox::Otw;
use moverox::traits::{MoveDatatype, MoveType};
use serde::{Deserialize, Serialize};

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

let address = "0x2".parse().unwrap();
let module = "sui".parse().unwrap();
let name = "SUI".parse().unwrap();
let sui_type = Otw::type_tag(address, module, name);
let balance_type = Balance::<Otw>::type_tag(sui_type);

Implementations

impl Otw

pub const fn type_tag( address: Address, module: Identifier, name: Identifier, ) -> OtwTypeTag

Create this type’s specialized type tag.

impl Otw

pub const fn new() -> Self

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 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 MoveDatatype for Otw

type StructTag = OtwTypeTag

impl MoveType for Otw

type TypeTag = OtwTypeTag

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 Eq for Otw

impl StructuralPartialEq for Otw
