Struct MergeEngine 

pub struct MergeEngine { /* private fields */ }

The three-way merge engine.

Construct with an SDL document, then call merge() with base/current/proposed values.

Implementations

impl MergeEngine

pub fn new(schema: SdlDocument) -> Self

Create a new merge engine from an SDL document.

The SDL document must be valid (call validate::sdl::validate_sdl() first if needed).

pub fn schema(&self) -> &SdlDocument

Return a reference to the SDL schema.

pub fn merge(&self, base: Value, current: Value, proposed: Value) -> MergeResult

Perform a three-way merge.

Pipeline

1. Normalize current and proposed against base.
2. Build path maps for all three documents.
3. Compute the union of all paths.
4. For each path, resolve values and apply merge strategy.
5. Check for identity mutations (protocol invariant).
6. Return merged result or conflicts.

Arguments

• base - The base (reference) document.
• current - The current (our) document.
• proposed - The proposed (their) document.

Returns

MergeResult::Merged(Value) on success, or MergeResult::Conflicts(Vec<Conflict>) if conflicts were found.
