Type Definition odbc_api::parameter::VarCharBox

pub type VarCharBox = VarChar<Box<[u8]>>;

Parameter type for owned, variable sized character data.

We use Box<[u8]> rather than Vec<u8> as a buffer type since the indicator pointer already has the role of telling us how many bytes in the buffer are part of the payload.
