Struct TokenIdUnit

pub struct TokenIdUnit();

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 Unit for representing token IDs, which means only one token ID can be represented with this type and other token IDs cannot be represented. For a more general token ID type see TokenIdVec.

Trait Implementations

impl Clone for TokenIdUnit

fn clone(&self) -> TokenIdUnit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenIdUnit

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

Formats the value using the given formatter.

impl Deserial for TokenIdUnit

The TokenIdUnit will deserialize one byte ensuring this contains the value 0. It will result in an error if the byte is not 0.

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 TokenIdUnit

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TokenIdUnit> for String

fn from(_id: TokenIdUnit) -> Self

Converts to this type from the input type.

impl Hash for TokenIdUnit

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 TokenIdUnit

fn cmp(&self, other: &TokenIdUnit) -> 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 TokenIdUnit

fn eq(&self, other: &TokenIdUnit) -> 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 TokenIdUnit

fn partial_cmp(&self, other: &TokenIdUnit) -> 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 TokenIdUnit

fn get_type() -> Type

impl Serial for TokenIdUnit

The TokenIdUnit is serialized with one byte with the value 0.

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 TokenIdUnit

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for TokenIdUnit

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for TokenIdUnit

impl Eq for TokenIdUnit

impl IsTokenId for TokenIdUnit

impl StructuralPartialEq for TokenIdUnit
