Struct OpenOptions 

pub struct OpenOptions {
    pub sheet_rows: Option<u32>,
    pub sheets: Option<Vec<String>>,
    pub max_unzip_size: Option<u64>,
    pub max_zip_entries: Option<usize>,
}

Options for controlling how a workbook is opened and parsed.

All fields default to None (no limit / parse everything). Use the builder-style setter methods for convenience.

Fields

sheet_rows: Option<u32>

Maximum number of rows to read per sheet. Rows beyond this limit are silently discarded during parsing.

sheets: Option<Vec<String>>

Only parse sheets whose names are in this list. Sheets not listed are represented as empty worksheets (their XML is not parsed). None means parse all sheets.

max_unzip_size: Option<u64>

Maximum total decompressed size of all ZIP entries in bytes. Exceeding this limit returns [Error::ZipSizeExceeded]. Default when None: no limit.

max_zip_entries: Option<usize>

Maximum number of ZIP entries allowed. Exceeding this limit returns [Error::ZipEntryCountExceeded]. Default when None: no limit.
