Errors that can occur when checking money transactions.

Variants

BadlyTyped

Dynamic typing issue. This error doesn’t discriminate between badly typed inputs and outputs.

NoEvictionsAllowed

The Money piece does not allow any evictions at all.

MintingWithInputs

The transaction attempts to consume inputs while minting. This is not allowed.

MintingNothing

The transaction attempts to mint zero coins. This is not allowed.

SpendingNothing

The transaction attempts to spend without consuming any inputs. Either the output value will exceed the input value, or if there are no outputs, it is a waste of processing power, so it is not allowed.

OutputsExceedInputs

The value of the spent input coins is less than the value of the newly created output coins. This would lead to money creation and is not allowed.

ValueOverflow

The value consumed or created by this transaction overflows the value type. This could lead to problems like https://bitcointalk.org/index.php?topic=823.0

ZeroValueCoin

The transaction attempted to create a coin with zero value. This is not allowed because it wastes state space.

Trait Implementations

impl Clone for ConstraintCheckerError

fn clone(&self) -> ConstraintCheckerError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintCheckerError

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

Formats the value using the given formatter.

impl Decode for ConstraintCheckerError

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for ConstraintCheckerError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for ConstraintCheckerError

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Hash for ConstraintCheckerError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ConstraintCheckerError

fn cmp(&self, other: &ConstraintCheckerError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ConstraintCheckerError

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

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

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

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

impl PartialOrd for ConstraintCheckerError

fn partial_cmp(&self, other: &ConstraintCheckerError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ConstraintCheckerError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for ConstraintCheckerError

type Identity = ConstraintCheckerError

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
