Typed failure from manifest-backed checked export lookup.

Variants

MissingSignatureMetadata

The manifest has no trusted signature entry for the requested symbol.

Fields

symbol: String

SignatureMismatch

The manifest signature does not match the requested Rust call shape.

Fields

symbol: String

expected: Box<LeanExportSignature>

manifest: Box<LeanExportSignature>

SymbolKindMismatch

The manifest’s function/global classification does not match the dylib.

Fields

symbol: String

manifest: LeanExportSymbolKind

actual: LeanExportSymbolKind

MissingSymbol

The manifest entry exists, but the symbol is absent from the loaded library.

Fields

symbol: String

source: LeanError

Module(LeanError)

The initialized module could not be reopened before lookup.

Trait Implementations

impl Debug for LeanCheckedExportError

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

Formats the value using the given formatter.

impl Display for LeanCheckedExportError

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

Formats the value using the given formatter.

impl Error for LeanCheckedExportError

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>)
