Implementations

impl PageRange

pub fn parse(s: &str) -> Result<Self, OperationError>

Parse a page range from a string

Examples:

• “all” -> All pages
• “1” -> Single page (converts to 0-based)
• “1-5” -> Range of pages (converts to 0-based)
• “1,3,5” -> List of pages (converts to 0-based)

pub fn get_indices( &self, total_pages: usize, ) -> Result<Vec<usize>, OperationError>

Get the page indices for this range
