Trait join_impl::expr_chain::expr::InnerExpr

pub trait InnerExpr where
    Self: Sized, {
    fn extract_inner(&self) -> Option<Vec<&Expr>>;
    fn replace_inner(&self, expr: Vec<Expr>) -> Option<Self>;

    fn is_replaceable(&self) -> bool { ... }
}

Provides functionality to get or replace inner Expr(s).

Required methods

fn extract_inner(&self) -> Option<Vec<&Expr>>

Extracts Expr(s) from given value if applicable.

fn replace_inner(&self, expr: Vec<Expr>) -> Option<Self>

Replaces current expr by given Expr if it's possible, returning Some(Self) with given Expr(s), otherwise returns None.
