Enum UnfoldDeclError 

pub enum UnfoldDeclError {
    DuplicateDeconstructor {
        target: String,
    },
    DuplicateOutput {
        func: Ident,
        target: DeconTarget,
    },
}

One structurally invalid output-expansion declaration (see UnfoldError::InvalidDeclarations). Note that EMPTY record lists are deliberately not diagnosed here — an empty inline list is the valid whole-element (Vec<T> per-element) delivery form.

Variants

DuplicateDeconstructor

Two deconstructor declarations for the same target type.

Fields

target: String

DuplicateOutput

Two per-fn output expansions for the same fn and position.

Fields

func: Ident

target: DeconTarget
