CompareBool returns a Predicate that compares zed.Values to a boolean literal that must be a boolean or coercible to an integer.

CompareFloat64 returns a Predicate that compares typed byte slices that must be coercible to an double with the value's double value using a comparison based on op.

Return a predicate for comparing this value to one more typed byte slices by calling the predicate function with a Value.

Comparison returns a Predicate that compares typed byte slices that must be TypeAddr with the value's address using a comparison based on op.

Comparison returns a Predicate that compares typed byte slices that must be an addr or a subnet to the value's subnet value using a comparison based on op.

Comparison returns a Predicate for comparing this value to other values.

Given a predicate for comparing individual elements, produce a new predicate that implements the "in" comparison.

DotExprToString returns Zed for the Evaluator assuming it's a field expr.

FlattenColumns turns nested records into a series of columns of the form "outer.inner".

NewArithmetic compiles an expression of the form "expr1 op expr2" for the arithmetic operators +, -, *, /.

NewCompareFn creates a function that compares a pair of Records based on the provided ordered list of fields.

NewConstShaper returns a shaper that will shape the result of expr to the provided shapeTo type.

NewCutter returns a Cutter for fieldnames.

NewFlattener returns a flattener that transforms nested records to flattened records where the type context of the received records must match the zctx parameter provided here.

NewRegexpBoolean returns a Booelan that compares values that must be a stringy the given regexp.

NewShaper returns a shaper that will shape the result of expr to the type returned by typExpr.

NewUnflattener returns a Unflattener that turns successive dotted field names into nested records.

SearchRecordOther creates a filter that searches zng records for the given value, which must be of a type other than (b)string.

SearchRecordString handles the special case of string searching -- it matches both field names and values.

SortStable performs a stable sort on the provided records.

BufferFilter is a filter for byte slices containing ZNG values.

Index represents an index operator "container[index]" where container is either an array (with index type integer) or a record (with index type string).

A TyepFunc returns a type value of the named type (where the name is a Zed typedef).

Predicate is a function that takes a Value and returns a boolean result based on the typed value.

A ShaperTransform represents one of the different transforms that a shaper can apply.
