Struct PathMapper 

pub struct PathMapper;

Path mapper for extracting and setting values in JSON using dot-notation paths

Implementations

impl PathMapper

pub fn get_path<'a>(obj: &'a Value, path: &str) -> Option<&'a Value>

Get value from JSON using dot-notation path (supports array indexing)

Examples:

• “choices[0].delta.content”
• “input.temperature”
• “delta.text”

pub fn get_string(obj: &Value, path: &str) -> Option<String>

Get string value from path (converts number to string if needed)

pub fn set_path( obj: &mut Value, path: &str, value: Value, ) -> Result<(), PathMapperError>

Set value at nested path in JSON object

Examples:

• “input.temperature” -> sets obj[“input”][“temperature”]
• “generationConfig.maxOutputTokens” -> sets obj[“generationConfig”][“maxOutputTokens”]

pub fn set_paths( obj: &mut Value, paths: &HashMap<String, Value>, ) -> Result<(), PathMapperError>

Batch set multiple paths
