Trait ReaderRef

pub trait ReaderRef<RS>: Reader<RS>
where
    RS: Read + Seek,
{
    // Required method
    fn worksheet_range_ref<'a>(
        &'a mut self,
        name: &str,
    ) -> Result<Range<DataRef<'a>>, Self::Error>;

    // Provided method
    fn worksheet_range_at_ref(
        &mut self,
        n: usize,
    ) -> Option<Result<Range<DataRef<'_>>, Self::Error>> { ... }
}

A trait to share spreadsheets reader functions across different FileTypes

Required Methods

fn worksheet_range_ref<'a>( &'a mut self, name: &str, ) -> Result<Range<DataRef<'a>>, Self::Error>

Get worksheet range where shared string values are only borrowed.

This is implemented only for [calamine::Xlsb] and [calamine::Xlsx], as Xls and Ods formats do not support lazy iteration.

Provided Methods

fn worksheet_range_at_ref( &mut self, n: usize, ) -> Option<Result<Range<DataRef<'_>>, Self::Error>>

Get the nth worksheet range where shared string values are only borrowed. Shortcut for getting the nth sheet_name, then the corresponding worksheet.

This is implemented only for [calamine::Xlsb] and [calamine::Xlsx], as Xls and Ods formats do not support lazy iteration.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
