Enum ExprKind 

#[non_exhaustive]
pub enum ExprKind<E = Expr> {
    Integer(i64),
    Real(NotNan<f64>),
    String(String),
    Symbol(Symbol),
    Normal(Normal<E>),
    ByteArray(Vec<u8>),
    Association(Vec<RuleEntry>),
    NumericArray(ArrayBuf<NumericArrayEnum>),
    PackedArray(ArrayBuf<PackedArrayEnum>),
    BigInteger(BigInteger),
    BigReal(BigReal),
}

Wolfram Language expression variants.

Marked #[non_exhaustive] so that future variant additions (for new WXF wire types, etc.) are non-breaking. Downstream match expressions over ExprKind from outside this crate must include a _ => … arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Integer(i64)

A machine (64-bit) integer.

Real(NotNan<f64>)

A machine (64-bit) real, guaranteed non-NaN.

String(String)

A string.

Symbol(Symbol)

A symbol such as System`Plus.

Normal(Normal<E>)

A normal expression head[args…] — see Normal.

ByteArray(Vec<u8>)

A ByteArray — a flat buffer of bytes.

Association(Vec<RuleEntry>)

An Association of key/value rules.

NumericArray(ArrayBuf<NumericArrayEnum>)

A NumericArray — a packed array of fixed-width numbers.

PackedArray(ArrayBuf<PackedArrayEnum>)

A PackedArray — a packed rectangular array of machine numbers.

BigInteger(BigInteger)

An arbitrary-precision integer.

BigReal(BigReal)

An arbitrary-precision real.
