Utility Functions Module

Path-based read/write helpers for the datavalue::OwnedDataValue tree that backs Message::context. The same dot-path syntax that worked on serde_json::Value works here unchanged — including #-prefix escapes for numeric object keys.

Functions

get_nested_value

Get a reference to the value at path, walking the tree.

get_nested_value_cloned

Clone the value at path, returning None if the path is unresolvable.

get_nested_value_parts

Same as get_nested_value but consumes a pre-split slice of path parts. Parts retain the original # prefix; strip_hash_prefix is applied at lookup time so the #20 → “force object key 20” semantics still hold.

set_nested_value

Set the value at path, creating intermediate containers as needed.

set_nested_value_parts

Same as set_nested_value but consumes a pre-split slice of path parts. Parts retain the original # prefix; strip_hash_prefix is applied at use time. Crucially, the “is the NEXT segment an array index?” decision looks at the raw (unstripped) parts[i+1] — #20 parses as non-numeric, so the child container is an Object (key “20”), not an Array.
