Implementations

impl JsonCursor

pub fn new() -> Self

pub fn next<'a>( &mut self, obj: &'a JsonValue ) -> Option<(String, &'a JsonValue)>

Walk the tree of a JSON object finding all the leaves. Any value that is not an object is considered a leaf. This may be called recursively.

pub fn parent<'a>(&self, obj: &'a JsonValue) -> Option<&'a JsonValue>

pub fn key_path(&self) -> Vec<String>

Return key to current leaf as list of strings. Note this includes the key that is returned with next.

pub fn key_path_string(&self) -> String

Return key to current leaf as a path string. This can have problems in case there are keys containing /, so key_path should always be preferred.
