#[repr(C)]
pub struct Symbol(_);
Expand description

Wolfram Language symbol.

PartialOrd sorting order

The comparison behavior of this type is NOT guaranteed to match the behavior of System`Order for symbols (and does not match it at the moment).

This type implements PartialOrd/Ord primarily for the purposes of allowing instances of this type to be included in ordered sets (e.g. BTreeMap).

Implementations

Attempt to parse input as an absolute symbol.

An absolute symbol is a symbol with an explicit context path. "System`Plus" is an absolute symbol, "Plus" is a relative symbol and/or a SymbolName. "`Plus" is also a relative symbol.

Construct a symbol from input.

Panics

This function will panic if input is not a valid Wolfram Language symbol. Symbol::try_new(input) must succeed.

This method is intended to be used for convenient construction of symbols from string literals, where an error is unlikely to occur, e.g.:

let expr = Expr::normal(Symbol::new("MyPackage`Foo"), vec![]);

If not using a string literal as the argument, prefer to use Symbol::try_new and handle the error condition.

Get the context path part of a symbol as an ContextRef.

Get the symbol name part of a symbol as a SymbolNameRef.

Get the underlying &str representation of this type.
