Struct EgldOrEsdtTokenIdentifier

Source
pub struct EgldOrEsdtTokenIdentifier<M>
where M: ManagedTypeApi,
{ /* private fields */ }
Expand description

Specialized type for handling either EGLD or ESDT token identifiers.

Equivalent to a structure of the form

enum EgldOrEsdtTokenIdentifier<M: ManagedTypeApi> {
    Egld,
    Esdt(TokenIdentifier<M>),
}

It is, however more optimized than that. Its implementation is based on ManagedOption.

EGLD is indicated by a special, invalid token identifier handle. This way we can fit it inside a single i32 in memory.

Implementations§

Source§

impl<M> EgldOrEsdtTokenIdentifier<M>
where M: ManagedTypeApi,

Source

pub const EGLD_REPRESENTATION: &'static [u8; 4] = b"EGLD"

This special representation is interpreted as the EGLD token.

Source

pub fn egld() -> EgldOrEsdtTokenIdentifier<M>

New instance of the special EGLD token representation.

Source

pub fn esdt<TI>(token_identifier: TI) -> EgldOrEsdtTokenIdentifier<M>
where TokenIdentifier<M>: From<TI>,

ESDT instance, containing an ESDT token identifier.

Source

pub fn parse(data: ManagedBuffer<M>) -> EgldOrEsdtTokenIdentifier<M>

Source

pub fn is_egld(&self) -> bool

Source

pub fn is_esdt(&self) -> bool

Source

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

Returns “EGLD” or the token identifier.

Source

pub fn is_valid(&self) -> bool

Checks the ESDT token identifier for validity. EGLD is considered valid, no checks needed.

Will fail if it encodes an invalid ESDT token identifier.

Source

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

Source

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

Source

pub fn to_boxed_bytes(&self) -> BoxedBytes

Source

pub fn map_or_else<Context, D, F, R>( self, context: Context, for_egld: D, for_esdt: F, ) -> R
where D: FnOnce(Context) -> R, F: FnOnce(Context, TokenIdentifier<M>) -> R,

Source

pub fn map_ref_or_else<Context, D, F, R>( &self, context: Context, for_egld: D, for_esdt: F, ) -> R
where D: FnOnce(Context) -> R, F: FnOnce(Context, &TokenIdentifier<M>) -> R,

Source

pub fn unwrap_esdt(self) -> TokenIdentifier<M>

Source

pub fn as_esdt_option(&self) -> Option<ManagedRef<'_, M, TokenIdentifier<M>>>

Representation of the object as an Option.

Because it does not consume self only a reference to the ESDT token identifier can be returned.

Source

pub fn into_esdt_option(self) -> Option<TokenIdentifier<M>>

Converts self into an Option. Consumes self in the process.

Source§

unsafe fn forget_into_handle( self, ) -> <EgldOrEsdtTokenIdentifier<M> as ManagedType<M>>::OwnHandle

Source§

fn transmute_from_handle_ref( handle_ref: &<M as HandleTypeInfo>::ManagedBufferHandle, ) -> &EgldOrEsdtTokenIdentifier<M>

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.
Source§

impl<M> ManagedVecItem for EgldOrEsdtTokenIdentifier<M>
where M: ManagedTypeApi,

Source§

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).
