Expressions
An Expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context. Expressions are special because they are evaluated before sending the result to a channel.
The following operators are used for building expressions:
Arithmetic operators
The supported arithmetic operators are: +, -, /, *.
Relational operators
The supported relational operators are: >, >=, <, <=',==,!=`.
Logical operators
The supported logical operators are: and, or, not.
Matches expression
The p matches q expression is similar to
1
2
3
4
match p {
q -> true
_ -> false
}
The difference between matches and the above is that the former is an expression.
