Usage

write_json_atomic(x, path)

Arguments

x

Object to write to JSON

path

Character string giving the file path

Value

Invisible NULL. Called for side effect.

Details

The function writes to a .tmp suffix file first, then uses file.rename() to atomically move it to the target path. If the rename fails, a bayesim_checkpoint_error is thrown.
