Enum PanicReason

#[non_exhaustive]
pub enum PanicReason {
    NotImplemented,
    UnmatchedPattern,
    FutureCompleted,
}

Pre-canned panic reasons.

To formulate a custom reason, use VmError::panic.

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.

NotImplemented

Not implemented.

UnmatchedPattern

A pattern didn’t match where it unconditionally has to.

FutureCompleted

Tried to poll a future that has already been completed.

Trait Implementations

impl Clone for PanicReason

fn clone(&self) -> PanicReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PanicReason

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

Formats the value using the given formatter.

impl<'__de, __A> Decode<'__de, Binary, __A> for PanicReason

where __A: Allocator,

const IS_BITWISE_DECODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

fn decode<T0>(_1: T0) -> Result<Self, <T0 as Decoder<'__de>>::Error>

where T0: Decoder<'__de, Mode = Binary, Allocator = __A>,

Decode the current value.

impl<'__de, __A> Decode<'__de, Text, __A> for PanicReason

where __A: Allocator,

const IS_BITWISE_DECODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

fn decode<T0>(_1: T0) -> Result<Self, <T0 as Decoder<'__de>>::Error>

where T0: Decoder<'__de, Mode = Text, Allocator = __A>,

Decode the current value.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PanicReason

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

Formats the value using the given formatter.

impl Encode<Binary> for PanicReason

const IS_BITWISE_ENCODE: bool = false
