Pretty writes a human-readable representation of an IR object to w.

Walk invokes the visitor for nodes under x.

Data is the local variable that refers to the global data document.

Input is the local variable that refers to the global input document.

Unused is the free local variable that can be allocated in a plan.

ArrayAppendStmt represents a dynamic append operation of a value onto an array.

AssignIntStmt represents an assignment of an integer value to a local variable.

AssignVarOnceStmt represents an assignment of one local variable to another.

AssignVarStmt represents an assignment of one local variable to another.

BlockStmt represents a nested block.

BreakStmt represents a jump out of the current block.

CallDynamicStmt represents an indirect (data) function call.

CallStmt represents a named function call.

LenStmt represents a length() operation on a local variable.

Location records the filen index, and the row and column inside that file that a statement can be connected to.

MakeArrayStmt constructs a local variable that refers to an array value.

MakeNullStmt constructs a local variable that refers to a null value.

MakeSetStmt constructs a local variable that refers to a set value.

NopStmt adds a nop instruction.

NotEqualStmt represents a != check of two local variables.

NotStmt represents a negated statement.

ObjectInsertOnceStmt represents a dynamic insert operation of a key/value pair into an object.

ObjectInsertStmt represents a dynamic insert operation of a key/value pair into an object.

ResultSetAddStmt adds a value into the result set returned by the query plan.

ReturnLocalStmt represents a return statement that yields a local value.

ScanStmt represents a linear scan over a composite value.

SetAddStmt represents a dynamic add operation of an element into a set.

WithStmt replaces the Local or a portion of the document referred to by the Local with the Value and executes the contained block.

Val represents an abstract value that statements operate on.

Visitor defines the interface for visiting IR nodes.

Bool represents a constant boolean.

StringIndex represents the index into the plan's list of constant strings of a constant string.
