Enum frame_support::pallet_prelude::TransactionSource

pub enum TransactionSource {
    InBlock,
    Local,
    External,
}

The source of the transaction.

Depending on the source we might apply different validation schemes. For instance we can disallow specific kinds of transactions if they were not produced by our local node (for instance off-chain workers).

Variants

InBlock

Transaction is already included in block.

This means that we can’t really tell where the transaction is coming from, since it’s already in the received block. Note that the custom validation logic using either Local or External should most likely just allow InBlock transactions as well.

Local

Transaction is coming from a local source.

This means that the transaction was produced internally by the node (for instance an Off-Chain Worker, or an Off-Chain Call), as opposed to being received over the network.

External

Transaction has been received externally.

This means the transaction has been received from (usually) “untrusted” source, for instance received over the network or RPC.

Trait Implementations

impl Clone for TransactionSource

fn clone(&self) -> TransactionSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionSource

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

Formats the value using the given formatter.

impl Decode for TransactionSource

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

Attempt to deserialise the value from input.

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 TransactionSource

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 size_hint(&self) -> usize

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

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 MallocSizeOf for TransactionSource

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. If T::size_of is a constant, consider implementing constant_size as well.

fn constant_size() -> Option<usize>where
    Self: Sized,

Used to optimize MallocSizeOf implementation for collections like Vec and HashMap to avoid iterating over them unnecessarily. The Self: Sized bound is for object safety.

impl PartialEq<TransactionSource> for TransactionSource

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