BinaryExpr
Cast
GetItem
IsNull
Let
Let expressions are of the form let var = bind in expr, see Scope.
Like
ListContains
Literal
Merge
Merge zero or more expressions that ALL return structs.
Not
Pack
Pack zero or more expressions into a structure with named fields.
Scope
Scope define the evaluation context/scope that an expression uses when being evaluated. There is a special Identifier (Identity) which is used to bind the initial array being evaluated

Traits§

AnalysisExpr
This can be used by expression to plug into vortex expression analysis, such as pruning or expression simplification
DynEq
VortexExpr can’t be constrained by Eq directly because it must remain object safe. To ease implementation blanket implementation is provided for Eq types.
ExprSerializable
StatsCatalog
VortexExpr
Represents logical operation on ArrayRefs
VortexExprExt
