pub struct ConversionError;
Expand description

Error type indicating a failure to convert some type to another; details of the failed conversion may be written to the debug log, when possible.

This is intentionally minimal and uninformative to minimize impact of its use on wasm codesize. It converts to Error(ScErrorType::Value, ScErrorCode::UnexpectedType) when converted to a full Error, and ideally it should only be used in ubiquitous cases that will occur in wasm, like small-number or tag conversions, where code size is paramount and the information-loss from using it is not too bad.
