Struct CellDiff 

#[non_exhaustive]
pub struct CellDiff {
    pub address: CellAddress,
    pub value: Option<ValueChange>,
    pub formula: Option<FormulaChange>,
    pub format: Option<FormatChange>,
    pub diagnostics: Vec<Diagnostic>,
}

A merged per-cell diff entry (RFC-033 §5).

One CellDiff per logical address. This is the intended consumer model: a value change and a formula change at the same address are facets of one change, carried in the independent value and formula sub-fields, not two separate entries. The output::view::CellChangeRow projection follows the same rule (one row per address, with formula_changed / old_formula / new_formula describing the formula facet). Consumers migrating from a per-facet model should collapse to one row per address rather than preserve the split.

change_kind() is derived from the sub-fields, not stored.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

address: CellAddress

value: Option<ValueChange>

formula: Option<FormulaChange>

format: Option<FormatChange>

Reserved until RFC-022.

diagnostics: Vec<Diagnostic>

Implementations

impl CellDiff

pub fn change_kind(&self) -> CellChangeKind

Derive Added / Removed / Modified from the sub-change fields.

• Added: every present sub-change has an empty/absent old side.
• Removed: every present sub-change has an empty/absent new side.
• Modified: otherwise.

This derivation is stable API: the rule above will not change within a major version, so downstream code may depend on it rather than re-deriving presence classification from the sub-fields.
