pub struct ZeroBlob(pub i32);
This is supported on crate feature
blob
only.Expand description
BLOB of length N that is filled with zeroes.
Zeroblobs are intended to serve as placeholders for BLOBs whose content is later written using incremental BLOB I/O routines.
A negative value for the zeroblob results in a zero-length BLOB.
