Functions

dynamic_to_json

pub fn dynamic_to_json(from value: Dynamic) -> JsonType

Converts any Dynamic into a JsonType which can be matched on to extract the data. If conversion fails for a given property, Unknown is returned.

parse

pub fn parse(from json: String) -> Result(JsonType, DecodeError)

Parses a string into a JsonType which can be matched on to extract the data. If decoding fails for a given property, Unknown is returned.

parse_dict

pub fn parse_dict(
  json: String,
) -> Result(Dict(Dynamic, Dynamic), DecodeError)

Parses a string into a Dict of Dynamic values

path

pub fn path(
  json: JsonType,
  path: String,
) -> Result(JsonType, Nil)

Select a nested value from a JsonType object using a path expression (e.g. “a.b.c[3]”). Returns Nil if the path does not lead to a value.
