Struct TokenIdentifier

pub struct TokenIdentifier<M: ErrorApi + ManagedTypeApi> { /* private fields */ }

Specialized type for handling token identifiers. It wraps a BoxedBytes with the full ASCII name of the token. EGLD is stored as an empty name.

Not yet implemented, but we might add additional restrictions when deserializing as argument.

Implementations

impl<M: ManagedTypeApi> TokenIdentifier<M>

pub unsafe fn esdt_unchecked(data: EgldOrEsdtTokenIdentifier<M>) -> Self

Creates a new TokenIdentifier without verifying that it is not EGLD-000000.

Safety

Calling it for the EGLD token might lead to unexpected bugs.

pub fn try_new(data: EgldOrEsdtTokenIdentifier<M>) -> Option<Self>

pub fn from_esdt_bytes<B: Into<ManagedBuffer<M>>>(bytes: B) -> Self

pub fn into_managed_buffer(self) -> ManagedBuffer<M>

pub fn as_managed_buffer(&self) -> &ManagedBuffer<M>

pub fn to_boxed_bytes(&self) -> BoxedBytes

pub fn is_valid_esdt_identifier(&self) -> bool

pub fn ticker(&self) -> ManagedBuffer<M>

impl<M: ManagedTypeApi> ManagedType<M> for TokenIdentifier<M>

type OwnHandle = <M as HandleTypeInfo>::ManagedBufferHandle

unsafe fn forget_into_handle(self) -> Self::OwnHandle

Forgets current object (does not run destructor), but extracts the handle.

fn transmute_from_handle_ref(handle_ref: &M::ManagedBufferHandle) -> &Self

Implement carefully, since the underlying transmutation is an unsafe operation. For types that wrap a handle to some VM-managed data, make sure the type only contains the handle (plus ZSTs if necessary). For types that just wrap another managed type it is easier, call for the wrapped object.

fn transmute_from_handle_ref_mut( handle_ref: &mut M::ManagedBufferHandle, ) -> &mut Self

fn get_raw_handle(&self) -> RawHandle

fn as_ref(&self) -> ManagedRef<'_, M, Self>

impl<M: ManagedTypeApi> ManagedVecItem for TokenIdentifier<M>

const SKIPS_RESERIALIZATION: bool = false

If true, then the encoding of the item is identical to the payload, and no further conversion is necessary (the underlying buffer can be used as-is during serialization). False for all managed types, but true for basic types (like u32).

type PAYLOAD = ManagedVecItemPayloadBuffer<4>

Type managing the underlying binary representation in a ManagedVec..

type Ref<'a> = ManagedRef<'a, M, TokenIdentifier<M>>

Reference representation of the ManagedVec item.

fn read_from_payload(payload: &Self::PAYLOAD) -> Self

Parses given bytes as a an owned object.

unsafe fn borrow_from_payload<'a>(payload: &Self::PAYLOAD) -> Self::Ref<'a>

fn save_to_payload(self, payload: &mut Self::PAYLOAD)

Converts the object into bytes.

where I: NestedDecodeInput, H: DecodeErrorHandler,

where I: NestedDecodeInput,

impl<M: ManagedTypeApi> TypeAbi for TokenIdentifier<M>

type Unmanaged = TokenIdentifier<M>

fn type_name() -> TypeName

fn type_name_rust() -> TypeName

fn type_names() -> TypeNames

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC, )

A type can provide more than its own name. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
