Struct xcm_simulator::XcmContext

pub struct XcmContext {
    pub origin: Option<Location>,
    pub message_id: [u8; 32],
    pub topic: Option<[u8; 32]>,
}

Contextual data pertaining to a specific list of XCM instructions.

Fields

origin: Option<Location>

The current value of the Origin register of the XCVM.

message_id: [u8; 32]

The identity of the XCM; this may be a hash of its versioned encoding but could also be a high-level identity set by an appropriate barrier.

topic: Option<[u8; 32]>

The current value of the Topic register of the XCVM.

Implementations

impl XcmContext

pub fn with_message_id(message_id: [u8; 32]) -> XcmContext

Constructor which sets the message ID to the supplied parameter and leaves the origin and topic unset.

Trait Implementations

impl Clone for XcmContext

fn clone(&self) -> XcmContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for XcmContext

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

Formats the value using the given formatter.

impl Decode for XcmContext

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<XcmContext, 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 Encode for XcmContext

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 PartialEq for XcmContext

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