pub struct OutputStringBuffer { /* private fields */ }
Expand description

We use this as an output buffer for strings. Allows for detecting truncation.

Implementations

Creates an empty string buffer. Useful if you want to e.g. use a prompt to complete the connection string, but are not interessted in the actual completed connection string.

Creates a new instance of an output string buffer which can hold strings up to a size of max_str_len - 1 characters. `-1 because one place is needed for the terminating zero. To hold a connection string the size should be at least 1024.

Ptr to the internal buffer. Used by ODBC API calls to fill the buffer.

Length of the internal buffer in characters including the terminating zero.

Mutable pointer to actual output string length. Used by ODBC API calls to report truncation.

Call this method to extract string from buffer after ODBC has filled it.

True if the buffer had not been large enough to hold the string.
