Fields

file: String

The file that failed to parse.

line: u32

The line number where the error occurred.

message: String

A description of the parse error.

MissingInterface

A required interface is missing from the component.

Fields

component: String

The component that is missing the interface.

interface_name: String

The name of the missing interface.

TypeMismatch

A type in the component does not match the expected contract.

Fields

interface_name: String

The interface where the mismatch occurred.

type_name: String

The name of the mismatched type.

expected: String

The expected type.

actual: String

The actual type found.

VersionIncompatible

The contract version is incompatible.

Fields

required: String

The required version.

provided: String

The provided version.

PackageNotFound

Trait Implementations

impl Clone for ContractError

fn clone(&self) -> ContractError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractError

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

Formats the value using the given formatter.

impl Display for ContractError

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

Formats the value using the given formatter.

impl Error for ContractError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ContractError> for TorvynError

fn from(e: ContractError) -> Self

Converts to this type from the input type.

impl PartialEq for ContractError

fn eq(&self, other: &ContractError) -> 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.
