Struct googapis::google::api::expr::v1beta1::Expr [−][src]
Expand description
An abstract representation of a common expression.
Expressions are abstractly represented as a collection of identifiers, select statements, function calls, literals, and comprehensions. All operators with the exception of the ‘.’ operator are modelled as function calls. This makes it easy to represent new operators into the existing AST.
All references within expressions must resolve to a [Decl][google.api.expr.v1beta1.Decl] provided at
type-check for an expression to be valid. A reference may either be a bare
identifier name
or a qualified identifier google.api.name
. References
may either refer to a value or a function declaration.
For example, the expression google.api.name.startsWith('expr')
references
the declaration google.api.name
within a [Expr.Select][google.api.expr.v1beta1.Expr.Select] expression, and
the function declaration startsWith
.
Fields
id: i32
Required. An id assigned to this node by the parser which is unique in a given expression tree. This is used to associate type information and other attributes to a node in the parse tree.
expr_kind: Option<ExprKind>
Required. Variants of expressions.
