Enum damn_vuln_blockchain::error::ChainError

pub enum ChainError {
    GenesisBlockAdditionError,
    InvalidBlockChain,
    InconsistentBlockAdition,
}

Errors that can occur when interacting with the blockchain

Variants

GenesisBlockAdditionError

when the a genesis block is passed to get added to a chain genesis blocks are supposed to be used only during chain intiation they are invalid when they are used elsewhere

InvalidBlockChain

Blockchain invalid when block.hash() != block.next().prev Occours when entire blockchain's validity is checked

InconsistentBlockAdition

Block inconsistent, block.hash() != chain.get_last_block*().get_hash()

Trait Implementations

impl Clone for ChainError

fn clone(&self) -> ChainError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChainError

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

Formats the value using the given formatter.

impl Display for ChainError

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

Formats the value using the given formatter.

impl Error for ChainError

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 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

impl PartialEq<ChainError> for ChainError

fn eq(&self, other: &ChainError) -> bool

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
