Enum CommandItem 

pub enum CommandItem {
    Row(Row),
    Metadata(ResultMetadata),
    ReturnStatus(i32),
    ReturnValue(CommandReturnValue),
    RowsAffected(u64),
}

An item produced by a CommandStream.

Variants

Row(Row)

A single row of data.

Metadata(ResultMetadata)

Metadata describing the upcoming rows.

ReturnStatus(i32)

The procedure’s RETURN value. Signed: RETURN -1 is -1.

ReturnValue(CommandReturnValue)

A return value, matching an OUT parameter.

RowsAffected(u64)

The number of rows an INSERT, UPDATE, DELETE or other non-SELECT statement affected. SELECTs and variable assignments produce none, as with SqlClient’s ExecuteNonQuery; see ExecuteResult::rows_affected.
