Represents a Solidity panic. Same as the Solidity definition.

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.

Generic = 0

Generic / unspecified error.

Generic compiler inserted panics.

Assert = 1

Used by the assert() builtin.

Thrown when you call assert with an argument that evaluates to false.

UnderOverflow = 17

Arithmetic underflow or overflow.

Thrown when an arithmetic operation results in underflow or overflow outside of an unchecked { ... } block.

DivisionByZero = 18

Division or modulo by zero.

Thrown when you divide or modulo by zero (e.g. 5 / 0 or 23 % 0).

EnumConversionError = 33

Enum conversion error.

Thrown when you convert a value that is too big or negative into an enum type.

StorageEncodingError = 34

Invalid encoding in storage.

Thrown when you access a storage byte array that is incorrectly encoded.

EmptyArrayPop = 49

Empty array pop.

Thrown when you call .pop() on an empty array.

ArrayOutOfBounds = 50

Array out of bounds access.

Thrown when you access an array, bytesN or an array slice at an out-of-bounds or negative index (i.e. x[i] where i >= x.length or i < 0).

ResourceError = 65

Resource error (too large allocation or too large array).

Thrown when you allocate too much memory or create an array that is too large.

InvalidInternalFunction = 81

Calling invalid internal function.

Thrown when you call a zero-initialized variable of internal function type.

Implementations

impl PanicKind

pub const fn from_number(value: u32) -> Option<Self>

Returns the panic code for the given number if it is a known one.

pub const fn as_str(self) -> &'static str

Returns the panic code’s string representation.

Trait Implementations

impl Clone for PanicKind

fn clone(&self) -> PanicKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PanicKind

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

Formats the value using the given formatter.

impl Default for PanicKind

fn default() -> PanicKind

Returns the “default value” for a type.

impl Display for PanicKind

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

Formats the value using the given formatter.

impl From<PanicKind> for Panic

fn from(value: PanicKind) -> Self

Converts to this type from the input type.

impl Hash for PanicKind

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 PanicKind

fn cmp(&self, other: &PanicKind) -> 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 PanicKind

fn eq(&self, other: &PanicKind) -> 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 PanicKind

fn partial_cmp(&self, other: &PanicKind) -> 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.
