Enum HistoryError 

pub enum HistoryError {
    Mmr(String),
    InvalidBranch(String),
    Corrupted(String),
    RuntimeBootstrap(String),
    Io(Error),
}

Errors returned by CommitHistory and verify_inclusion.

Variants

Mmr(String)

The underlying MMR rejected the operation (out-of-bounds proof, invalid size, etc.). The wrapped string is commonware’s own Display impl — stable enough for logs, not parsed.

InvalidBranch(String)

The branch name failed crate::refs::validate_ref_name.

Corrupted(String)

On-disk journal could not be opened or recovered. commonware’s own init performs roll-forward recovery on a half-written trailing leaf (see commonware_storage::merkle::mmr::full docs); this variant surfaces failures it cannot recover from.

RuntimeBootstrap(String)

Failed to bootstrap the commonware tokio Context.

Io(Error)

Failed to set up the on-disk history directory.

Trait Implementations

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<Error> for HistoryError

fn from(source: Error) -> Self

Converts to this type from the input type.
