Register a builder for an artifact path — st_register

A "builder" knows how to (re)create an artifact. It will be called by st_rebuild() as fun(path, parents) and must return a list:


  list(
    x = <object to save>,           # required
    format = NULL,                  # optional ("qs2", "rds", ...)
    metadata = list(),              # optional, merged into sidecar
    code = NULL,                    # optional (function/expr/character)
    code_label = NULL               # optional (short description)
  )

Usage

st_register_builder(path, fun, name = NULL)

Arguments

path: Character path this builder produces (exact match).
fun: Function with signature function(path, parents).
name: Optional label so you can register multiple builders per path.

Value

Invisibly TRUE.
