Struct OpenCursor 

pub struct OpenCursor {
    pub with_hold: bool,
    pub positioned: bool,
    pub statement: Option<String>,
    pub held: VecDeque<Vec<Value>>,
    pub current: usize,
    pub rowset_size: Option<u32>,
}

Fields

with_hold: bool

positioned: bool

On a row, so a positioned UPDATE or DELETE has one to change.

statement: Option<String>

The prepared statement a cursor for one runs.

held: VecDeque<Vec<Value>>

The rows from the current position’s first: the current rowset’s, then those a rowset FETCH read ahead of a row FETCH, which moves from the rowset’s first row (Db2 13 SQL, FETCH, Table 6).

current: usize

How many of held the current position takes, 0 before the first.

rowset_size: Option<u32>

The rows the last FETCH asked for, when it was a rowset FETCH, which the next asks for again without FOR n ROWS.
