Enum conv::errors::GeneralError

pub enum GeneralError<T> {
    NegOverflow(T),
    PosOverflow(T),
    Unrepresentable(T),
}

A general error enumeration that subsumes all other conversion errors.

This exists primarily as a "catch-all" for reliably unifying various different kinds of conversion errors.

Variants

NegOverflow(T)

Input was too negative for the target type.

PosOverflow(T)

Input was too positive for the target type.

Unrepresentable(T)

Input was not representable in the target type.
