Struct nu_protocol::value::column_path::ColumnPath [−][src]
pub struct ColumnPath { /* fields omitted */ }
Expand description
The fundamental path primitive to describe how to navigate through a table to get to a sub-item. A path member can be either a word or a number. Words/strings are taken to mean a column name, and numbers are the row number. Taken together they describe which column or row to narrow to in order to get data.
Rows must follow column names, they can’t come first. eg) foo.1
is valid where 1.foo
is not.
