Struct dharitri_wasm::types::MoaxOrDctTokenIdentifier

pub struct MoaxOrDctTokenIdentifier<M: ManagedTypeApi> { /* private fields */ }

Specialized type for handling either MOAX or DCT token identifiers.

Equivalent to a structure of the form

enum MoaxOrDctTokenIdentifier<M: ManagedTypeApi> {
    Moax,
    Dct(TokenIdentifier<M>),
}

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

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

Implementations

impl<M: ManagedTypeApi> MoaxOrDctTokenIdentifier<M>

pub const MOAX_REPRESENTATION: &'static [u8; 4] = _

This special representation is interpreted as the MOAX token.

pub fn moax() -> Self

New instance of the special MOAX token representation.

pub fn dct<TI>(token_identifier: TI) -> Self

where TokenIdentifier<M>: From<TI>,

DCT instance, containing an DCT token identifier.

pub fn from_opt_raw_handle(opt_handle: Option<M::ManagedBufferHandle>) -> Self

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

pub fn is_moax(&self) -> bool

pub fn is_dct(&self) -> bool

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

pub fn is_valid(&self) -> bool

Checks the DCT token identifier for validity. MOAX is considered valid, no checks needed.

Will fail if it encodes an invalid DCT token identifier.

pub fn map_or_else<U, D, F>(self, for_moax: D, for_dct: F) -> U

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

pub fn map_ref_or_else<U, D, F>(&self, for_moax: D, for_dct: F) -> U

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

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

pub fn as_dct_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 DCT token identifier can be returned.

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

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

Trait Implementations

impl<M: Clone + ManagedTypeApi> Clone for MoaxOrDctTokenIdentifier<M>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<M> Debug for MoaxOrDctTokenIdentifier<M>

where M: ManagedTypeApi,

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

Formats the value using the given formatter.

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

const PAYLOAD_SIZE: usize = 4usize

Size of the data stored in the underlying ManagedBuffer.

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 Ref<'a> = MoaxOrDctTokenIdentifier<M>

Reference representation of the ManagedVec item.

fn from_byte_reader<Reader: FnMut(&mut [u8])>(reader: Reader) -> Self

Parses given bytes as a an owned object.

unsafe fn from_byte_reader_as_borrow<'a, Reader: FnMut(&mut [u8])>( reader: Reader ) -> Self::Ref<'a>

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

fn to_byte_writer<R, Writer: FnMut(&[u8]) -> R>(&self, writer: Writer) -> R

impl<M: ManagedTypeApi> NestedDecode for MoaxOrDctTokenIdentifier<M>

fn dep_decode_or_handle_err<I, H>( input: &mut I, h: H ) -> Result<Self, H::HandledErr>

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.

impl<M: ManagedTypeApi> NestedEncode for MoaxOrDctTokenIdentifier<M>

fn dep_encode_or_handle_err<O, H>( &self, dest: &mut O, h: H ) -> Result<(), H::HandledErr>

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.

impl<M: ManagedTypeApi> PartialEq<MoaxOrDctTokenIdentifier<M>> for TokenIdentifier<M>

fn eq(&self, other: &MoaxOrDctTokenIdentifier<M>) -> 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<M: ManagedTypeApi> PartialEq<TokenIdentifier<M>> for MoaxOrDctTokenIdentifier<M>

fn eq(&self, other: &TokenIdentifier<M>) -> 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.

fn eq(&self, other: &Self) -> 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.

fn top_decode<I>(input: I) -> Result<Self, DecodeError>

where I: TopDecodeInput,

Attempt to deserialize the value from input.

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

fn type_name() -> TypeName

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

A type can provide more than its own description. 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.
