Enum DigStoreError 

pub enum DigStoreError {
    InvalidSize(String),
    SizeProofMismatch {
        anchored_k: u8,
        actual_k: u8,

}

Everything that can go wrong composing, spending, or reading a DIG store.

Variants

InvalidSize(String)

A size value is outside the valid ladder (k ∈ 0..=10, i.e. 1 MB..1 GB) — see crate::SizeBucket. Mirrors dig_merkle::MerkleError::InvalidSize.

SizeProofMismatch

A downloaded .dig’s real size does not match the size the store anchored on chain, so it MUST be discarded rather than stored or served (SPEC §4, NC-9). Carries the anchored bucket and the observed byte length for diagnostics.

Fields

anchored_k: u8

The power-of-2 exponent the store anchored on chain.

actual_k: u8

The power-of-2 exponent the downloaded .dig’s real byte length falls into.

actual_bytes: u64

The downloaded .dig’s real byte length.

InvalidUrn(String)

A URN string could not be parsed or a store id / root hash was malformed.

Proof(String)

An on-chain read could not prove the store’s integrity/validity against the chain (NC-9): the coin was absent, the lineage did not verify, or the chain source failed.

Capsule(String)

The underlying .dig capsule (dig-capsule) could not be opened, parsed, or read, or its declared store_id did not match a trusted anchor. Returned by the off-chain capsule getters (crate::get_capsule_identity / crate::open_capsule, SPEC §5/§11): unreadable/tampered module bytes and a store_id-vs-anchor mismatch both surface here (fail-closed).

Spend(String)

A spend could not be constructed by the on-chain anchor (dig-merkle).

Trait Implementations

impl Debug for DigStoreError

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

Formats the value using the given formatter.

impl Display for DigStoreError

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

Formats the value using the given formatter.

impl Error for DigStoreError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<MerkleError> for DigStoreError

fn from(error: MerkleError) -> Self

Maps a dig-merkle failure into the store taxonomy. An out-of-range size stays an DigStoreError::InvalidSize; every other dig-merkle error is a spend-construction failure (DigStoreError::Spend). Read paths that need the DigStoreError::Proof framing map explicitly at the call site rather than through this conversion.
