Struct RewaOrDcdtTokenIdentifier

pub struct RewaOrDcdtTokenIdentifier<M>
where
    M: ManagedTypeApi,
{ /* private fields */ }

Specialized type for handling either REWA or DCDT token identifiers.

Equivalent to a structure of the form

enum RewaOrDcdtTokenIdentifier<M: ManagedTypeApi> {
    Rewa,
    Dcdt(TokenIdentifier<M>),
}

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

REWA a special, invalid token identifier handle. This way we can fit it inside a single i32 in memory.

Implementations

impl<M> RewaOrDcdtTokenIdentifier<M>

where M: ManagedTypeApi,

pub const REWA_REPRESENTATION: &'static [u8; 4]

This special representation is interpreted as the REWA token.

pub fn rewa() -> RewaOrDcdtTokenIdentifier<M>

New instance of the special REWA token representation.

pub fn dcdt<TI>(token_identifier: TI) -> RewaOrDcdtTokenIdentifier<M>

where TokenIdentifier<M>: From<TI>,

DCDT instance, containing an DCDT token identifier.

pub fn from_opt_raw_handle( opt_handle: Option<<M as HandleTypeInfo>::ManagedBufferHandle>, ) -> RewaOrDcdtTokenIdentifier<M>

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

pub fn is_rewa(&self) -> bool

pub fn is_dcdt(&self) -> bool

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

pub fn is_valid(&self) -> bool

Checks the DCDT token identifier for validity. REWA is considered valid, no checks needed.

Will fail if it encodes an invalid DCDT token identifier.

pub fn map_or_else<Context, D, F, R>( self, context: Context, for_rewa: D, for_dcdt: F, ) -> R

where D: FnOnce(Context) -> R, F: FnOnce(Context, TokenIdentifier<M>) -> R,

pub fn map_ref_or_else<Context, D, F, R>( &self, context: Context, for_rewa: D, for_dcdt: F, ) -> R

where D: FnOnce(Context) -> R, F: FnOnce(Context, &TokenIdentifier<M>) -> R,

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

pub fn as_dcdt_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 DCDT token identifier can be returned.

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

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

Trait Implementations

impl<M> Clone for RewaOrDcdtTokenIdentifier<M>

where M: Clone + ManagedTypeApi,

fn clone(&self) -> RewaOrDcdtTokenIdentifier<M>

Returns a copy of the value.

Formats the value using the given formatter.

impl<M> ManagedVecItem for RewaOrDcdtTokenIdentifier<M>

where M: ManagedTypeApi,

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 = <(ManagedOption<M, TokenIdentifier<M>>, ()) as ManagedVecItemNestedTuple>::PAYLOAD

Type managing the underlying binary representation in a ManagedVec..

type Ref<'a> = RewaOrDcdtTokenIdentifier<M>

Reference representation of the ManagedVec item.

fn from_byte_reader<Reader>(reader: Reader) -> RewaOrDcdtTokenIdentifier<M>

where Reader: FnMut(&mut [u8]),

Parses given bytes as a an owned object.

unsafe fn from_byte_reader_as_borrow<'a, Reader>( reader: Reader, ) -> <RewaOrDcdtTokenIdentifier<M> as ManagedVecItem>::Ref<'a>

where Reader: FnMut(&mut [u8]),

Parses given bytes as a representation of the object, either owned, or a reference.

where I: NestedDecodeInput, H: DecodeErrorHandler,

Version of dep_decode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn dep_decode<I>(input: &mut I) -> Result<Self, DecodeError>

where I: NestedDecodeInput,

Attempt to deserialise the value from input, using the format of an object nested inside another structure. In case of success returns the deserialized value and the number of bytes consumed during the operation.

where O: NestedEncodeOutput, H: EncodeErrorHandler,

Version of dep_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn dep_encode<O>(&self, dest: &mut O) -> Result<(), EncodeError>

where O: NestedEncodeOutput,

NestedEncode to output, using the format of an object nested inside another structure. Does not provide compact version.
