Struct LetStatement 

pub struct LetStatement {
    pub let_token: Let,
    pub ident: Punctuated<VariableDefinition, Comma>,
    pub eq: Eq,
    pub expr: Expression<true>,
    pub rule: Option<(RuleOperator, Expression<true>)>,
    pub semi: Semi,
}

let <something> = <something else>. Defines variables and possibly adds rules to them.

Fields

let_token: Let

The let token.

ident: Punctuated<VariableDefinition, Comma>

The lhs ident iterator.

eq: Eq

The = token.

expr: Expression<true>

The rhs expression.

rule: Option<(RuleOperator, Expression<true>)>

The rule after the rhs expression.

semi: Semi

The ending semicolon.
