Struct yamlpath::Query

source · 
pub struct Query { /* private fields */ }
Expand description

A query into some YAML document.

Internally, a query is one or more “component” selectors, each of which is either a mapping key or list index to descend through.

For example, with the following YAML document:

foo:
  bar:
    baz:
      - [a, b, c]
      - [d, e, f]

The sub-list member e would be identified via the path foo, bar, baz, 1, 1.
