Trait Implementations

impl CandidType for TokenMetadata

fn _ty() -> Type

fn id() -> TypeId

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

where __S: Serializer,

fn ty() -> Type

impl Clone for TokenMetadata

fn clone(&self) -> TokenMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TokenMetadata

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Storable for TokenMetadata

const BOUND: Bound = ic_stable_structures::storable::Bound::Unbounded

The size bounds of the type.

fn to_bytes(&self) -> Cow<'_, [u8]>

Converts an element into bytes.

fn from_bytes(bytes: Cow<'_, [u8]>) -> Self

Converts bytes into an element.

fn to_bytes_checked(&self) -> Cow<'_, [u8]>

Like to_bytes, but includes additional checks to ensure the element’s serialized bytes are within the element’s bounds.
