pub struct MirRelationExprDeserializeContext<'a> {
pub(crate) inner_ctx: MirScalarExprDeserializeContext,
pub(crate) catalog: &'a TestCatalog,
pub(crate) scope: Scope,
}Expand description
Extends the test case syntax to support MirRelationExprs
A new context should be created for the deserialization of each MirRelationExpr because the context stores state local to each MirRelationExpr.
Includes all the test case syntax extensions to support MirScalarExprs.
The following variants of MirRelationExpr have non-standard syntax:
Let -> the syntax is (let x <value> <body>) where x is an ident that
should not match any existing ident in any Let statement in
<value>.
Get -> the syntax is (get x), where x is an ident that refers to a
pre-defined source or an ident defined in a let.
Union -> the syntax is (union <input1> .. <inputn>).
Constant -> the syntax is
(constant
[[<row1literal1>..<row1literaln>]..[<rowiliteral1>..<rowiliteraln>]]
<RelationType>
)For convenience, a usize can be alternately specified as #n.
We recommend specifying a usize as #n instead of n when the usize
is a column reference.
