Error that can occur while preparing or executing Wasm smart-contract.

Variants

Serialization = 0

Error happened while serializing the module.

Deserialization = 1

Error happened while deserializing the module.

InternalMemoryDeclared = 2

Internal memory declaration has been found in the module.

GasInstrumentation = 3

Gas instrumentation failed.

This most likely indicates the module isn’t valid.

StackHeightInstrumentation = 4

Stack instrumentation failed.

This most likely indicates the module isn’t valid.

Instantiate = 5

Error happened during instantiation.

This might indicate that start function trapped, or module isn’t instantiable and/or un-linkable.

Memory = 6

Error creating memory.

TooManyFunctions = 7

Contract contains too many functions.

TooManyLocals = 8

Contract contains too many locals.

TooManyTables = 9

Contract contains too many tables.

TooManyTableElements = 10

Contract contains too many table elements.

FunctionBodyTooLarge = 11

A function body in the contract exceeds the size limit.

InstrumentedCodeTooLarge = 12

The instrumented code exceeds the size limit.

TooManyBlocksPerFunction = 13

A function contains too many basic blocks.

TooManyBlocksPerContract = 14

A contract contains too many basic blocks.

TooManyTypes = 15

Contract declares too many entries in the wasm type section.

TooManyParamsPerFunction = 16

All contract functions combined have more than max_params_per_contract parameters.

TooManyParamsPerContract = 17

A function has more than max_params_per_function parameters.

OperandStackTooLarge = 18

A function’s max operand-stack size (in bytes) exceeds max_operand_stack_bytes_per_function.

Trait Implementations

impl BorshDeserialize for PrepareError

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for PrepareError

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for PrepareError

fn clone(&self) -> PrepareError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrepareError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PrepareError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EnumExt for PrepareError

fn deserialize_variant<__R: Read>( reader: &mut __R, variant_tag: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

impl Eq for PrepareError

impl PartialEq for PrepareError

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for PrepareError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
