A trait to share spreadsheets reader functions accross different FileTypes

Associated Types

type RS: Read + Seek

Inner reader type

type Error: Debug + From<Error>

Error specific to file type

Required Methods

fn new(reader: Self::RS) -> Result<Self, Self::Error>

Creates a new instance.

fn vba_project(&mut self) -> Option<Result<Cow<VbaProject>, Self::Error>>

Gets VbaProject

fn metadata(&self) -> &Metadata

Initialize

fn worksheet_range(
    &mut self,
    name: &str
) -> Option<Result<Range<DataType>, Self::Error>>

Read worksheet data in corresponding worksheet path

fn worksheet_formula(
    &mut self,
    _: &str
) -> Option<Result<Range<String>, Self::Error>>

Read worksheet formula in corresponding worksheet path

Provided Methods

fn sheet_names(&self) -> &[String]

Get all sheet names of this workbook

Examples

use calamine::{Xlsx, open_workbook, Reader};

let mut workbook: Xlsx<_> = open_workbook(path).unwrap();
println!("Sheets: {:#?}", workbook.sheet_names());

fn defined_names(&self) -> &[(String, String)]

Get all defined names (Ranges names etc)
