[−]
[src]
pub struct Expression<N: Num> { pub string: String, pub ctx: Context<N>, pub term: Term<N>, }
The main Expression struct. Contains the string that was originally requested to be parsed, the context the Expression was parsed with, and the Term the raw form was parsed as. For just the parsed version of the expression, use the Term enum.
Fields
string: String
The original string passed into this expression
ctx: Context<N>
Context the expression was parsed with
term: Term<N>
The term this string has been parsed as
