Struct ReceiptMetadata 

#[non_exhaustive]
pub struct ReceiptMetadata {
    pub verifier_parameters: Digest,
}

Metadata providing context on the receipt.

It contains information about the proving system, SDK versions, and other information to help with interoperability. It is not cryptographically bound to the receipt, and should not be used for security-relevant decisions, such as choosing whether or not to accept a receipt based on it’s stated version.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

verifier_parameters: Digest

Information which can be used to decide whether a given verifier is compatible with this receipt (i.e. that it may be able to verify it).

It is intended to be used when there are multiple verifier implementations (e.g. corresponding to multiple versions of a proof system or circuit) and it is ambiguous which one should be used to attempt verification of a receipt.

Trait Implementations

impl BorshDeserialize for ReceiptMetadata

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for ReceiptMetadata

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for ReceiptMetadata

fn clone(&self) -> ReceiptMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReceiptMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReceiptMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReceiptMetadata

fn eq(&self, other: &ReceiptMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ReceiptMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
