Struct Approval 

pub struct Approval {
    pub owner: Address,
    pub spender: Address,
    pub token_id: U256,
}

Emitted when a specific NFT is approved to an account/contract

Fields

owner: Address

The address of the owner.

spender: Address

The address of the approved spender.

token_id: U256

The ID of the approved token.

Implementations

impl Approval

pub fn new(owner: Address, spender: Address, token_id: U256) -> Self

Creates a new instance of the Approval event.

Trait Implementations

impl CLTyped for Approval

fn cl_type() -> CLType

The CLType of Self.

impl Debug for Approval

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

Formats the value using the given formatter.

impl EventInstance for Approval

fn name() -> String

Returns the name of the event.

fn schema() -> Schema

Returns the Schema of the event.

impl FromBytes for Approval

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

Deserializes the slice into Self.

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

Deserializes the Vec<u8> into Self.

impl NamedCLTyped for Approval

fn ty() -> NamedCLType

Returns the NamedCLType of the implementing type.

impl PartialEq for Approval

fn eq(&self, other: &Approval) -> 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 SchemaCustomTypes for Approval

fn schema_types() -> Vec<Option<CustomType>>

Returns a vector of optional CustomTypes.

impl ToBytes for Approval

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.

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

where Self: Sized,

Consumes self and serializes to a Vec<u8>.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

impl Eq for Approval
