ListPatch

Struct ListPatch 

Source
pub struct ListPatch {
    pub replace_all: Option<Vec<String>>,
    pub clear: bool,
    pub remove: Vec<String>,
    pub replace: Vec<(String, String)>,
    pub after: Vec<(String, Vec<String>)>,
    pub before: Vec<(String, Vec<String>)>,
    pub prepend: Vec<String>,
    pub add: Vec<String>,
}
Expand description

A patch over an inherited ordered string list. Either a wholesale replace_all (a plain TOML array) or a set of in-place edits applied to the inherited base, in this order: clearremovereplaceafter / beforeprependadd. The result is de-duplicated, keeping the first occurrence (order-stable).

Fields§

§replace_all: Option<Vec<String>>

Plain-array form: replace the inherited list outright (then dedup).

§clear: bool

Start from an empty list instead of the inherited base.

§remove: Vec<String>

Drop every element equal to one of these.

§replace: Vec<(String, String)>

Swap an element in place, preserving its position: (old, new).

§after: Vec<(String, Vec<String>)>

Insert items immediately after an anchor element: (anchor, items). No-op if the anchor is absent.

§before: Vec<(String, Vec<String>)>

Insert items immediately before an anchor element: (anchor, items).

§prepend: Vec<String>

Insert at the front (before the inherited elements).

§add: Vec<String>

Append at the end.

Implementations§

Source§

impl ListPatch

Source

pub fn apply(&self, base: &[String]) -> Vec<String>

Apply the patch to base, returning the resulting order-stable, de-duped list.

Source

pub fn is_noop(&self) -> bool

True when the patch makes no change (no override declared).
