Struct StoreValidator 

pub struct StoreValidator<S> { /* private fields */ }

Available on crate feature std only.

A validator that uses a BatchStore for validation.

This validator performs comprehensive validation:

1. Retrieves the batch from the store
2. Checks the batch is usable (enough confirmations)
3. Checks the batch is not expired
4. Validates the stamp index is within bounds
5. Validates the bucket matches the chunk address
6. Verifies the stamp signature matches the batch owner

Example

use nectar_postage::{StoreValidator, BatchStore};

let store = MyBatchStore::new();
let validator = StoreValidator::new(store, 50); // 50 block confirmations

let result = validator.validate(&stamp, &address).await;

Implementations

impl<S> StoreValidator<S>

pub const fn new(store: S, confirmation_threshold: u64) -> Self

Creates a new store validator.

Arguments

• store - The batch store to use for lookups
• confirmation_threshold - Minimum block confirmations for a batch to be usable

pub const fn store(&self) -> &S

Returns a reference to the underlying store.

pub const fn confirmation_threshold(&self) -> u64

Returns the confirmation threshold.

impl<S: BatchStore + Sync> StoreValidator<S>

pub async fn validate( &self, stamp: &Stamp, address: &SwarmAddress, ) -> Result<(), StampError>

Validates a stamp asynchronously.

This performs full validation including signature verification.

Returns

Ok(()) if the stamp is valid, or a StampError describing the failure.

pub async fn validate_structure( &self, stamp: &Stamp, address: &SwarmAddress, ) -> Result<(), StampError>

Validates the structural properties without signature verification.

This is faster than full validation when you only need to check that the stamp references a valid batch and bucket.

impl<S: Debug> Debug for StoreValidator<S>

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

Formats the value using the given formatter.
