Type Alias frame_system::pallet::Origin

pub type Origin<T> = RawOrigin<<T as Config>::AccountId>;

Exposed trait-generic origin type.

Aliased Type

enum Origin<T> {
    Root,
    Signed(<T as Config>::AccountId),
    None,
}

Variants

Root

The system itself ordained this dispatch to happen: this is the highest privilege level.

Signed(<T as Config>::AccountId)

It is signed by some public key and we provide the AccountId.

None

It is signed by nobody, can be either:

• included and agreed upon by the validators anyway,
• or unsigned transaction validated by a pallet.

Implementations

impl<AccountId> RawOrigin<AccountId>

pub fn as_signed(&self) -> Option<&AccountId>

Returns Some with a reference to the AccountId if self is Signed, None otherwise.

pub fn is_root(&self) -> bool

Returns true if self is Root, None otherwise.

pub fn is_none(&self) -> bool

Returns true if self is None, None otherwise.

Trait Implementations

impl<AccountId> Clone for RawOrigin<AccountId>

where AccountId: Clone,

fn clone(&self) -> RawOrigin<AccountId>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<AccountId> Debug for RawOrigin<AccountId>

where AccountId: Debug,

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

Formats the value using the given formatter.

impl<AccountId> Decode for RawOrigin<AccountId>

where AccountId: Decode,

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<RawOrigin<AccountId>, Error>

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<AccountId> Encode for RawOrigin<AccountId>

where AccountId: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<AccountId> From<Option<AccountId>> for RawOrigin<AccountId>

fn from(s: Option<AccountId>) -> RawOrigin<AccountId>

Converts to this type from the input type.

impl<AccountId> MaxEncodedLen for RawOrigin<AccountId>

where AccountId: MaxEncodedLen,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<AccountId> PartialEq for RawOrigin<AccountId>

where AccountId: PartialEq,

fn eq(&self, other: &RawOrigin<AccountId>) -> 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<AccountId> TypeInfo for RawOrigin<AccountId>

where AccountId: TypeInfo + 'static,

type Identity = RawOrigin<AccountId>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
