Enum FunctionCallError

pub enum FunctionCallError {
    CompilationError(CompilationError),
    LinkError {
        msg: String,
    },
    MethodResolveError(MethodResolveError),
    WasmTrap(WasmTrap),
    HostError(HostError),
}

Permitted errors that cause a function call to fail gracefully.

Occurrence of such errors will be included in the merklize state on chain using a single bit to signal failure vs Success.

See the doc comment on VMResult for an explanation what the difference between this and a VMRunnerError is. And see PartialExecutionStatus for what gets stored on chain.

Variants

CompilationError(CompilationError)

Wasm compilation error

LinkError

Wasm binary env link error

Fields

msg: String

MethodResolveError(MethodResolveError)

Import/export resolve error

WasmTrap(WasmTrap)

A trap happened during execution of a binary

HostError(HostError)

Trait Implementations

impl Debug for FunctionCallError

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

Formats the value using the given formatter.

impl Display for FunctionCallError

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

Formats the value using the given formatter.

impl<'_derivative_strum> From<&'_derivative_strum FunctionCallError> for &'static str

fn from(x: &'_derivative_strum FunctionCallError) -> &'static str

Converts to this type from the input type.

impl From<FunctionCallError> for &'static str

fn from(x: FunctionCallError) -> &'static str

Converts to this type from the input type.

impl From<PrepareError> for FunctionCallError

fn from(err: PrepareError) -> Self

Converts to this type from the input type.

impl PartialEq for FunctionCallError

fn eq(&self, other: &FunctionCallError) -> 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 TryFrom<VMLogicError> for FunctionCallError

Try to convert a general error that happened at the VMLogic level to a FunctionCallError that can be included in a VMOutcome.

VMLogicError have two very different types of errors. Some are just a result from the guest code doing incorrect things, other are bugs in unc-infra. The first type can be converted to a FunctionCallError, the other becomes a VMRunnerError instead and must be treated differently.

type Error = VMRunnerError

The type returned in the event of a conversion error.

fn try_from(err: VMLogicError) -> Result<Self, Self::Error>

Performs the conversion.
