Module tree 

Declarative completion-tree builders derived from command and config metadata. Declarative builders for the completion engine’s immutable tree model.

Public API shape:

• describe command surfaces with CommandSpec
• lower them into a cached crate::completion::CompletionTree with CompletionTreeBuilder
• keep the resulting tree as plain data so the engine and embedders can reuse it without retaining builder state

Structs

CommandSpec

Declarative command description used to build a completion tree.

CompletionTreeBuilder

Builds immutable completion trees from command and config metadata.

ConfigKeySpec

Declarative config set key metadata used for completion nodes.

Enums

CompletionTreeBuildError

Error returned when declarative completion metadata cannot be lowered into a valid immutable tree.
