Struct TokenIdU16

pub struct TokenIdU16(pub u16);

Token Identifier, which combined with the address of the contract instance, forms the unique identifier of a token type.

The CIS2 specification allows for up to 255 bytes for the token ID, but for most cases using a smaller token ID is fine and can reduce contract energy costs.

This token ID uses u16 for representing the token ID bytes which means the token ID space is fixed to 2 bytes and some token IDs cannot be represented. For a more general token ID type see TokenIdVec.

Trait Implementations

impl Clone for TokenIdU16

fn clone(&self) -> TokenIdU16

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenIdU16

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

Formats the value using the given formatter.

impl Deserial for TokenIdU16

The TokenIdU16 will deserialize one byte ensuring this contains the value 2 and then deserialize a u16 as little endian. It will result in an error if the first byte is not 2.

fn deserial<R: Read>(source: &mut R) -> ParseResult<Self>

Attempt to read a structure from a given source, failing if an error occurs during deserialization or reading.

impl<'de> Deserialize<'de> for TokenIdU16

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TokenIdU16

Display the token ID as a uppercase hex string

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

Formats the value using the given formatter.

impl From<TokenIdU16> for String

fn from(id: TokenIdU16) -> Self

Converts to this type from the input type.

impl From<u16> for TokenIdU16

fn from(id: u16) -> Self

Converts to this type from the input type.

impl FromStr for TokenIdU16

Parse the token ID from a hex string

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for TokenIdU16

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 Ord for TokenIdU16

fn cmp(&self, other: &TokenIdU16) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TokenIdU16

fn eq(&self, other: &TokenIdU16) -> 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 PartialOrd for TokenIdU16

fn partial_cmp(&self, other: &TokenIdU16) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SchemaType for TokenIdU16

fn get_type() -> Type

impl Serial for TokenIdU16

The TokenIdU16 is serialized with one byte with the value 2 followed by 2 bytes to encode a u16 in little endian.

fn serial<W: Write>(&self, out: &mut W) -> Result<(), W::Err>

Attempt to write the structure into the provided writer, failing if only part of the structure could be written.

impl Serialize for TokenIdU16

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
