Statement attributes. Each statement is a list of 0 or more fields. Fields may only appear once and in the order declared here.

Variants

AuthenticityProof(Proof)

Statement proof.

DecryptionKey(DecryptionKey)

An identifier for the key that Data field may be decrypted with.

Priority(u32)

Priority when competing with other messages from the same sender.

Channel(Channel)

Account channel to use. Only one message per (account, channel) pair is allowed.

Topic1(Topic)

First statement topic.

Topic2(Topic)

Second statement topic.

Topic3(Topic)

Third statement topic.

Topic4(Topic)

Fourth statement topic.

Data(Vec<u8>)

Additional data.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl Decode for Field

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

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 Encode for Field

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere 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 PartialEq<Field> for Field

fn eq(&self, other: &Field) -> 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 TypeInfo for Field

type Identity = Field

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl EncodeLike<Field> for Field

impl Eq for Field

impl StructuralEq for Field

impl StructuralPartialEq for Field
