Enum ReadErrorKind 

#[non_exhaustive]
pub enum ReadErrorKind {
    SheetNotFound,
    MalformedSheet,
    Other,
}

Why a sheet could not be read.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SheetNotFound

The workbook’s own sheet index names a sheet that could not be located when reading it. Sound reasoning for the CLI’s exit-code mapping (3, alongside MalformedSheet) rests on there being no way to ask for a specific sheet: this crate always reads every sheet the index promises, so a missing one is the workbook’s own internal inconsistency, not a caller’s request for something that was never going to exist. If a sheet-selection option is ever added, this variant becomes reachable as caller error too, and the exit-code mapping would need to move to 2 for that case.

MalformedSheet

The sheet exists but its content could not be parsed.

Other

Cannot occur through any input this crate currently accepts: the workbook reader is Xlsx<Cursor<Vec<u8>>>, so every sheet read operates on an in-memory cursor — there is no I/O left to fail against at that point, and the XlsxError::Io case this variant exists for cannot arise there. A match arm on this variant is unreachable today; it is retained as a conservative default (see exit_code_for in main.rs) against a future reader that performs real I/O mid-read, not as a live case.
