Enum opaque_pointer::error::PointerError[−]

pub enum PointerError {
    Null,
    Invalid,
    Utf8Error(Utf8Error),
}
Expand description

Errors that can be detected by the functions of this crate.

Of course, invalid address can not be detected, then it’s unsafe yet.

Variants

Null
Invalid
Expand description

A pointer that was not previously lent to the FFI user.

Utf8Error(Utf8Error)
Expand description

Trying to convert to &str a C string which content is not valid UTF-8.
