Trait ckb_db::iter::DBIterator

pub trait DBIterator {
    fn iter_opt(
        &self, 
        col: Col, 
        mode: IteratorMode<'_>, 
        readopts: &ReadOptions
    ) -> Result<DBIter<'_>>;

    fn iter(&self, col: Col, mode: IteratorMode<'_>) -> Result<DBIter<'_>> { ... }
}

An iterator over a column family, with specifiable ranges and direction.

Required methods

fn iter_opt(
    &self,
    col: Col,
    mode: IteratorMode<'_>,
    readopts: &ReadOptions
) -> Result<DBIter<'_>>

Opens an interator using the provided IteratorMode and ReadOptions. This is used when you want to iterate over a specific ColumnFamily with a modified ReadOptions

Provided methods

fn iter(&self, col: Col, mode: IteratorMode<'_>) -> Result<DBIter<'_>>

Opens an interator using the provided IteratorMode. This is used when you want to iterate over a specific ColumnFamily
