Implementations
sourceimpl<'a, T> Iterator<'a, T> where
T: Packer + PrimaryValueInterface + Default,
impl<'a, T> Iterator<'a, T> where
T: Packer + PrimaryValueInterface + Default,
sourcepub fn get_primary(&self) -> Option<u64>
pub fn get_primary(&self) -> Option<u64>
get primary key of iterator
access TableI64 to extract primary key from value if primary key is not cached
pub fn set_primary(&mut self, primary: u64)
sourcepub fn is_end(&self) -> bool
pub fn is_end(&self) -> bool
return true if it’s an end iterator, else false
use this method to check the return value of MultiIndex.end or TableI64.end
sourcepub fn expect_not_ok(self, msg: &str) -> Self
pub fn expect_not_ok(self, msg: &str) -> Self
help function for asserting on invalid iterator
