Enum Patch 

pub enum Patch {
    Replace {
        target: String,
        with: CExpr,
    },
    Delete {
        target: String,
    },
    WrapWith {
        target: String,
        wrapper: CExpr,
    },
}

Variants

Replace

Replace the node at target with the given expression fragment. Only CExpr nodes are supported (typed positions like type expressions and patterns are out-of-scope for this op).

Fields

target: String

with: CExpr

Delete

Delete a CExpr from a list-shaped parent. Currently supports Block.statements[i]. Deleting the result expression of a Block or any non-list parent is rejected.

Fields

target: String

WrapWith

Wrap the target expression with wrapper. The wrapper must contain exactly one Var { name: "_HOLE_" } node, which is substituted by the original target.

Fields

target: String

wrapper: CExpr
