Enum PluginOp 

pub enum PluginOp {
    Keep(usize),
    Modify(usize, DirectiveWrapper),
    Insert(DirectiveWrapper),
    Delete(usize),
}

One operation in a PluginOutput’s ordered op list.

Ops describe how each output directive relates to the input:

• PluginOp::Keep — reuse input[i] unchanged. Span and file_id preserved.
• PluginOp::Modify — output a new wrapper, but inherit input[i]’s source identity (span / file_id). Plugins use this when transforming an existing directive’s content (e.g., adding tags) so error reporting still points at the original source location.
• PluginOp::Insert — emit a fresh directive with synthesized source location (SYNTHESIZED_FILE_ID, zero span). Use for directives the plugin invents from scratch.
• PluginOp::Delete — drop input[i]. Must be explicit; omitting an index without Delete is a protocol violation that the host reports as a plugin error.

Variants

Keep(usize)

Reuse input[i] unchanged (preserves original span + file_id).

Modify(usize, DirectiveWrapper)

Replace input[i]’s content with wrapper, but inherit input[i]’s source identity (span + file_id).

Insert(DirectiveWrapper)

Insert a fresh directive with synthesized source location.

Delete(usize)

Drop input[i]. Must be explicit — see type-level docs.
