Stateless JSON, base64, and token helpers.

Implementations

impl DataHelpers

pub fn serialize<T: Serialize>(value: &T) -> Result<String, Error>

Serializes a value to a JSON string. Returns an error when serialization fails.

pub fn deserialize<T: DeserializeOwned>(s: &str) -> Result<T, Error>

Deserializes a value from a JSON string. Returns an error on invalid input.

pub fn to_base64(s: &str) -> String

Encodes a UTF-8 string as standard base64.

pub fn from_base64(s: &str) -> Result<String, DecodeError>

Decodes standard base64 to a string, replacing invalid UTF-8 sequences. Returns an error when the input is not valid base64.

pub fn create_token(len: usize) -> String

Creates a random alphanumeric token of length len.

pub fn create_token_range( min: usize, max: usize, _range: usize, _prefix: &str, _alphanum: bool, ) -> String

Creates a random alphanumeric token with a length chosen in [min, max]. Uses min when max <= min. _range, _prefix, and _alphanum are ignored.

pub fn to_json<T: Serialize>(v: &T) -> Value

Converts a value to serde_json::Value, returning Null when conversion fails.
