Struct Error

pub struct Error { /* private fields */ }

A leveldb error, just containing the error string provided by leveldb.

Implementations

impl Error

pub fn new(message: String) -> Error

create a new Error, using the String provided

pub unsafe fn new_from_char(message: *const c_char) -> Error

create an error from a c-string buffer.

This method is unsafe because the pointer must be valid and point to heap. The pointer will be passed to free!
