To support format conversion, just implement the ToWolfram trait.
rust
pub trait ToWolfram {
fn to_wolfram(&self) -> WolframValue;
fn to_wolfram_string(&self) -> String {self.to_wolfram().to_string()}
fn to_wolfram_bytes(&self) -> Vec<u8> {self.to_wolfram().to_bytes()}
fn to_wolfram_solid(&self) -> Vec<u8> {self.to_wolfram().to_compressed()}
}
WolframValue consists of the following legal elements:
rust
pub enum WolframValue {
/// Function with name, args
Boolean(bool),
Function(Box<str>, Vec<WolframValue>),
String(Box<str>),
Bytes(Vec<u8>),
Symbol(Box<str>),
Integer8(i8),
Integer16(i16),
Integer32(i32),
Integer64(i64),
BigInteger(BigInt),
/// Do not use `f64`, because partial order cannot be defined
Decimal64([u8; 8]),
BigDecimal(Box<str>),
/// Need to optimize
PackedArray(Vec<WolframValue>),
/// Need to optimize
NumericArray(Vec<WolframValue>),
/// Record with key, rule, value
Association(BTreeMap<WolframValue, (WolframValue, WolframValue)>),
Rule,
RuleDelayed,
}
Here are some common formats supported now:
rust
pub enum SupportedFormat {
JSON, //json
TOML, //toml
YAML, //yaml, yml
Pickle, //pkl
}
Because rust cannot define traits and structs externally at the same time, supporting new formats needs to be done within this project.
