```
pub trait PageReader: Iterator<Item = Result<Page>> + Send {
/// Gets the next page in the column chunk associated with this reader.
/// Returns `None` if there are no pages left.
fn get_next_page(&mut self) -> Result<Option<Page>>;
}
```
change to
```
pub trait PageReader: Iterator<Item = Result<Page>> + Send {
/// Gets the next page in the column chunk associated with this reader.
/// Returns `None` if there are no pages left.
fn get_next_page(&mut self) -> Result<Option<Page>>;
/// Gets the next page in the column chunk associated with this reader.
/// Returns `None` if there are no pages left.
fn get_next_page_header(&mut self) -> Result<Option<PageHeader>>;
}
```
i want to add `skip_page` in PageReader (for page index) need check page
header before call `skip_page` (
can not skip `DictionaryPage` `IndexPage`),
but now read header is in `get_next_page`, so extract it to a new func.
**Describe the solution you'd like**
A clear and concise description of what you want to happen.
**Describe alternatives you've considered**
put `skip_page` in `get_next_page`
**Additional context**
