Struct ProviderTrustSignal 

#[non_exhaustive]
pub struct ProviderTrustSignal {
    pub provider: PublicKey,
    pub signal: TrustSignalKind,
    pub hash: Option<Hash>,
    pub reporter: PublicKey,
    pub timestamp: u64,
    pub sequence: u64,
    pub signature: Option<String>,
}

A fetch or integrity observation published by a trusted reporter.

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.

provider: PublicKey

signal: TrustSignalKind

hash: Option<Hash>

reporter: PublicKey

timestamp: u64

sequence: u64

signature: Option<String>

Implementations

impl ProviderTrustSignal

pub fn new( provider: PublicKey, kind: TrustSignalKind, hash: Option<Hash>, reporter: PublicKey, timestamp: u64, sequence: u64, ) -> Result<Self>

Create an unsigned signal and validate its structure.

Errors

Returns an error when the signal structure is invalid.

pub fn new_with_time( provider: PublicKey, kind: TrustSignalKind, hash: Option<Hash>, sequence: u64, signing_key: &SigningKey, ) -> Result<Self>

Create and sign a signal using the current time.

Errors

Returns an error when the signal structure is invalid or signing fails.

pub fn from_trust_record( record: &ProviderTrustRecord, signing_key: &SigningKey, ) -> Result<Self>

Create a signed trust signal from a local provider trust record.

Maps ProviderTrustAction::Vouch to ObservedSuccess (positive observation) and ProviderTrustAction::Distrust to ObservedFailure (negative observation). Only vouch and distrust records can be converted; Trust, Warn, and other actions return an error.

Errors

Returns an error when the action is not vouch/distrust or when signing fails.

pub fn sign(&mut self, signing_key: &SigningKey) -> Result<()>

Errors

Returns an error when the signing key does not match the reporter.

pub fn sign_with_secret_key(&mut self, secret_key: &SecretKey) -> Result<()>

Errors

Returns an error when the signing key does not match the reporter.

pub fn verify(&self) -> Result<()>

Errors

Returns an error when the signal is malformed, expired, or unsigned.

pub fn verify_at(&self, now: u64) -> Result<()>

Errors

Returns an error when the signal is malformed, expired, or unsigned.

pub fn validate(&self) -> Result<()>

Errors

Returns an error when an identity or sequence is invalid.

pub fn to_bytes(&self) -> Result<Vec<u8>>

Errors

Returns an error when the signal is malformed or serialization fails.

pub fn from_bytes(bytes: impl AsRef<[u8]>) -> Result<Self>

Errors

Returns an error when the bytes do not contain a valid signal.
