Struct risc0_zkvm::SegmentReceipt

pub struct SegmentReceipt {
    pub seal: Vec<u32>,
    pub index: u32,
    pub hashfn: String,
}

A receipt attesting to the execution of a Segment.

A SegmentReceipt attests that a [crate::Segment] was executed in a manner consistent with the ReceiptMetadata included in the receipt.

Fields

seal: Vec<u32>

The cryptographic data attesting to the validity of the code execution.

This data is used by the ZKP Verifier (as called by SegmentReceipt::verify_with_context) to cryptographically prove that this Segment was faithfully executed. It is largely opaque cryptographic data, but contains a non-opaque metadata component, which can be conveniently accessed with SegmentReceipt::get_metadata.

index: u32

Segment index within the Receipt

hashfn: String

Name of the hash function used to create this receipt.

Implementations

impl SegmentReceipt

pub fn verify_with_context( &self, ctx: &VerifierContext ) -> Result<(), VerificationError>

Verify the integrity of this receipt.

pub fn get_metadata(&self) -> Result<ReceiptMetadata, VerificationError>

Returns the ReceiptMetadata for this receipt.

pub fn get_seal_bytes(&self) -> Vec<u8>

Return the seal for this receipt, as a vector of bytes.

Trait Implementations

impl Clone for SegmentReceipt

fn clone(&self) -> SegmentReceipt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SegmentReceipt

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SegmentReceipt

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SegmentReceipt

fn eq(&self, other: &SegmentReceipt) -> 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 Serialize for SegmentReceipt

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<SegmentReceipt> for Asset

type Error = Error

The type returned in the event of a conversion error.

fn try_from(segment_receipt: SegmentReceipt) -> Result<Self>

Performs the conversion.
