Module options 

Comparison options and builder (DiffOptions, DiffOptionsBuilder, …). Comparison options, builder, and related policy enums (RFC-006, RFC-033 §11).

Structs

ComparisonOptions

All comparison-behaviour options.

DiagnosticOptions

DiffOptions

The top-level configuration entry point for a v2 comparison.

DiffOptionsBuilder

Fluent builder for DiffOptions.

ExecutionOptions

Execution, progress, and cancellation options.

Limits

Resource bounds that protect against pathological workbooks.

MatchingOptions

Options controlling sheet matching and cell alignment.

OutputOptions

Output and presentation options.

ValueCompareOptions

All value-comparison policy fields grouped together.

Enums

AlignmentMode

Row/column alignment mode (RFC-011).

DateComparePolicy

How date/time values are compared.

DiffEvent

An event emitted during a comparison for progress reporting.

ExecutionMode

Execution-mode configuration.

FormatCompareMode

Controls whether cell formatting (number format, font, fill, …) is compared.

FormulaCompareMode

How formula text is compared when both sides have a formula.

NumberComparePolicy

How two floating-point numbers are compared.

NumericTypePolicy

Whether Integer vs Number is treated as a type change.

SheetMatchingMode

How sheets are paired between the two workbooks.

TypeMismatchPolicy

How a typed value is compared against a value of a different type.

Constants

DEFAULT_MAX_ALIGNMENT_PRODUCT

Default bound on the row-alignment m × n table (RFC-035 §5.1, §9).

DEFAULT_MAX_INPUT_BYTES

Default bound on input size, checked before any read begins (RFC-035 §5.4): 500 MiB. Chosen to be generous enough that no ordinary .xlsx workbook — this crate does not compare macros, embedded media, or other content that would make a legitimate file huge — should ever reach it, while still being finite.

Traits

Cancellation

Trait for cancellation predicates.

ProgressSink

Trait for receiving progress events.
