Function write_to_dir 

pub fn write_to_dir(
    dir: &Path,
    name: &str,
    description: &str,
    scope: MemoryScope,
    tags: &[String],
    body: &str,
) -> Result<PathBuf>

Write a memory into dir (created if needed). Returns the file path. Testable core of write_memory.

Errors

Creating dir and writing the file. A name that slugifies to an existing file is not an error — the memory is overwritten, which is how an update works.
