Enum trie_db::TrieError

pub enum TrieError<T, E> {
    InvalidStateRoot(T),
    IncompleteDatabase(T),
    ValueAtIncompleteKey(Vec<u8>, u8),
    DecoderError(T, E),
    InvalidHash(T, Vec<u8>),
}

Trie Errors.

These borrow the data within them to avoid excessive copying on every trie operation.

Variants

InvalidStateRoot(T)

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

IncompleteDatabase(T)

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(T, E)

Corrupt Trie item

InvalidHash(T, Vec<u8>)

Trait Implementations

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

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

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

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

Formats the value using the given formatter.

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

impl<T, E> Error for TrieError<T, E> where
    T: Debug,
    E: Error, 

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
