Built-in Reducer: Merge List — reducer_merge

A functional reducer that performs a deep merge of two named lists. It uses utils::modifyList internally, ensuring that existing keys are overwritten by new values while preserving other keys.

Usage

reducer_merge_list(current, new)

Arguments

current: The current list in the state.
new: The new list to merge in.

Value

A single merged list.

Examples

if (FALSE) { # \dontrun{
# Deep merging configuration or results
current_cfg <- list(params = list(temp = 0.5, top_p = 1.0), tags = "v1")
new_cfg <- list(params = list(temp = 0.7), tags = "v2")

# modifyList behavior ensured: tags is replaced, params is merged
merged <- reducer_merge_list(current_cfg, new_cfg)
str(merged)
# list(params = list(temp = 0.7, top_p = 1.0), tags = "v2")
} # }
