Enum ArrayMergeStrategy 

pub enum ArrayMergeStrategy {
    Replace,
    Append,
    Prepend,
    Index,
    Unique,
}

Strategy for merging arrays.

Defines how arrays should be combined when both base and overlay contain values at the same path.

Examples

use cfgmatic_merge::{Merge, MergeBehavior, ArrayMergeStrategy, MergeOptions};
use serde_json::json;

let base = json!([1, 2]);
let overlay = json!([3, 4]);

// Append: [1, 2, 3, 4]
let opts = MergeOptions::new()
    .behavior(MergeBehavior::Deep)
    .array_strategy(ArrayMergeStrategy::Append);

Variants

Replace

Replace array entirely with overlay.

This is the default behavior.

Append

Append overlay elements after base elements.

Results in [base..., overlay...].

Prepend

Prepend overlay elements before base elements.

Results in [overlay..., base...].

Index

Merge by index (element-wise).

Requires both arrays to have the same length. Each element at index i in the result comes from overlay.

Errors

Returns MergeError::InvalidValue if array lengths differ.

Unique

Deduplicate and merge all elements.

Preserves order of first occurrence. Null values are skipped.

Trait Implementations

impl Clone for ArrayMergeStrategy

fn clone(&self) -> ArrayMergeStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArrayMergeStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ArrayMergeStrategy

fn default() -> ArrayMergeStrategy

Returns the “default value” for a type.

impl PartialEq for ArrayMergeStrategy

fn eq(&self, other: &ArrayMergeStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
