Enum HistoryError 

#[non_exhaustive]
pub enum HistoryError {
    Ref(RefError),
    Store(StoreError),
    Mmb(String),
    InvalidBranch(String),
    Corrupted(String),
    Io(Error),
}

#[non_exhaustive]: which commonware-storage structure backs the proof (MMR, MMB, or a future replacement — see the module doc) is an internal implementation detail, not part of the contract this error type documents; the Mmb variant’s name is itself already the result of one such internal swap (from Mmr) and had no other reason to be a breaking rename. Same rationale crate::ops::gc::GcRootsError documents for its own #[non_exhaustive].

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ref(RefError)

Store(StoreError)

Mmb(String)

InvalidBranch(String)

Corrupted(String)

Io(Error)

Trait Implementations

impl Debug for HistoryError

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

Formats the value using the given formatter.

impl Display for HistoryError

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

impl Error for HistoryError

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
