NEP-148-compatible metadata struct

Fields

spec: String

Version of the NEP-148 spec

name: String

Human-friendly name of the token contract

symbol: String

Short, ideally unique string to concisely identify the token contract

icon: Option<String>

String representation (HTTP URL, data URL, IPFS, Arweave, etc.) of an icon for this token

reference: Option<String>

External (off-chain) URL to additional JSON metadata for this token contract

reference_hash: Option<Base64VecU8>

Hash of the content that should be present in the reference field. For tamper protection.

decimals: u8

Cosmetic. Number of base-10 decimal places to shift the floating point. 18 is a common value.

Trait Implementations

impl BorshDeserialize for FungibleTokenMetadatawhere
    String: BorshDeserialize,
    Option<String>: BorshDeserialize,
    Option<Base64VecU8>: BorshDeserialize,
    u8: BorshDeserialize,

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

impl BorshSerialize for FungibleTokenMetadatawhere
    String: BorshSerialize,
    Option<String>: BorshSerialize,
    Option<Base64VecU8>: BorshSerialize,
    u8: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

impl Clone for FungibleTokenMetadata

fn clone(&self) -> FungibleTokenMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FungibleTokenMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FungibleTokenMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<FungibleTokenMetadata> for FungibleTokenMetadata

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for FungibleTokenMetadata

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

Serialize this value into the given Serde serializer.
