Enum SelectExpr 

pub enum SelectExpr {
    Binsof {
        cp: String,
        bin: Option<String>,
        intersect: Option<Vec<RangeItem>>,
    },
    Not(Box<SelectExpr>),
    And(Box<SelectExpr>, Box<SelectExpr>),
    Or(Box<SelectExpr>, Box<SelectExpr>),
    With {
        sel: Box<SelectExpr>,
        expr: Expr,
        matches: Matches,
    },
    All,
    Set {
        expr: Expr,
        matches: Matches,
    },
}

A select_expression (Syntax 19-4).

Variants

Binsof

binsof(cp) / binsof(cp.bin), optionally intersect { ranges }. bin names one bin, or a whole b[] / b[N] array by its base name.

Fields

cp: String

bin: Option<String>

intersect: Option<Vec<RangeItem>>

Not(Box<SelectExpr>)

And(Box<SelectExpr>, Box<SelectExpr>)

Or(Box<SelectExpr>, Box<SelectExpr>)

With

sel with (expr) [matches ...]. The kernel receives the constructor arguments followed by one value per cross item, in item order.

Fields

sel: Box<SelectExpr>

expr: Expr

matches: Matches

All

The enclosing cross’s own identifier: every bin tuple.

Set

cross_set_expression [matches ...]: evaluates to a super::value::Val::List of tuples (each a Val::List with one value per cross item), 19.6.1.4.

Fields

expr: Expr

matches: Matches
