Struct InterfaceView 

pub struct InterfaceView {
    pub interface_id: Option<Identifier>,
    pub view_status: Option<Status>,
    pub view_value: Option<Record>,
    pub implementation_package_id: String,
}

View of a create event matched by an interface filter.

Fields

interface_id: Option<Identifier>

The interface implemented by the matched event. The identifier uses the package-id reference format.

Required

view_status: Option<Status>

Whether the view was successfully computed, and if not, the reason for the error. The error is reported using the same rules for error codes and messages as the errors returned for API requests.

Required

view_value: Option<Record>

The value of the interface’s view method on this event. Set if it was requested in the InterfaceFilter and it could be successfully computed.

Optional

implementation_package_id: String

The package defining the interface implementation used to compute the view. Can be different from the package that was used to create the contract itself, as the contract arguments can be upgraded or downgraded using smart-contract upgrading as part of computing the interface view. Populated if the view computation is successful, otherwise empty.

Optional

Trait Implementations

impl Clone for InterfaceView

fn clone(&self) -> InterfaceView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InterfaceView

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

Formats the value using the given formatter.

impl Default for InterfaceView

fn default() -> InterfaceView

Returns the “default value” for a type.

impl Message for InterfaceView

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,
