Type Alias TrieError

pub type TrieError<H> = TrieError<H, Error<H>>;

As in trie_db, but less generic, error type for the crate.

Aliased Type

enum TrieError<H> {
    InvalidStateRoot(H),
    IncompleteDatabase(H),
    ValueAtIncompleteKey(Vec<u8>, u8),
    DecoderError(H, Error<H>),
    InvalidHash(H, Vec<u8>),
}

Variants

InvalidStateRoot(H)

Attempted to create a trie with a state root not in the DB.

IncompleteDatabase(H)

Trie item not found in the database,

ValueAtIncompleteKey(Vec<u8>, u8)

A value was found in the trie with a nibble key that was not byte-aligned. The first parameter is the byte-aligned part of the prefix and the second parameter is the remaining nibble.

DecoderError(H, Error<H>)

Corrupt Trie item.

InvalidHash(H, Vec<u8>)

Hash is not value.

Trait Implementations

impl<T, E> Clone for TrieError<T, E>

where T: Clone, E: Clone,

fn clone(&self) -> TrieError<T, E>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, E> Debug for TrieError<T, E>

where T: Debug, E: Debug,

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

Formats the value using the given formatter.

impl<T, E> Display for TrieError<T, E>

where T: MaybeDebug, E: MaybeDebug,

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

Formats the value using the given formatter.

impl<T, E> Error for TrieError<T, E>

where T: Debug, E: Error,

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<T, E> PartialEq for TrieError<T, E>

where T: PartialEq, E: PartialEq,

fn eq(&self, other: &TrieError<T, E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T, E> Eq for TrieError<T, E>

where T: Eq, E: Eq,

impl<T, E> StructuralPartialEq for TrieError<T, E>
