Enum BridgeError 

pub enum BridgeError {
    UnknownDataCon(DataConId),
    UnknownDataConName(String),
    ArityMismatch {
        con: DataConId,
        expected: usize,
        got: usize,
    },
    TypeMismatch {
        expected: String,
        got: String,
    },
    UnsupportedType(String),
    InternalError(String),
}

Errors that can occur when bridging between Rust types and Core Values.

Variants

UnknownDataCon(DataConId)

The DataConId was not found in the DataConTable.

UnknownDataConName(String)

The DataConId was found, but it has an unexpected name.

ArityMismatch

The number of fields in a constructor does not match the expected arity.

Fields

con: DataConId

The constructor identifier.

expected: usize

The expected number of fields.

got: usize

The actual number of fields received.

TypeMismatch

The value has an unexpected type (e.g., expected a Literal, got a Con).

Fields

expected: String

A description of the expected type.

got: String

A description of the actual type received.

UnsupportedType(String)

The type is not supported by the bridge.

InternalError(String)

Internal invariant violation (should never happen).

Trait Implementations

impl Clone for BridgeError

fn clone(&self) -> BridgeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BridgeError

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

Formats the value using the given formatter.

impl Display for BridgeError

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

Formats the value using the given formatter.

impl Error for BridgeError

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 PartialEq for BridgeError

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