Package syntax documents the syntax used by benchmark filter and projection expressions.

NewFilter constructs a result filter from a boolean filter expression, such as ".name:Copy /size:4k".

NewKeyHeader computes the KeyHeader of a slice of Keys by combining common prefixes of fields.

NonSingularFields returns the subset of Fields for which at least two of keys have different values.

SortKeys sorts a slice of Keys using Key.Less.

A Field is a single field of a Projection.

A Filter filters benchmarks and benchmark observations.

A Key is an immutable tuple mapping from Fields to strings whose structure is given by a Projection.

A KeyHeader represents a slice of Keys, combined into a forest of trees by common Field values.

KeyHeaderNode is a node in a KeyHeader.

A Match records the set of result measurements that matched a filter query.

A Projection extracts some subset of the fields of a benchfmt.Result into a Key.

A ProjectionParser parses one or more related projection expressions.
