pub struct Template { /* private fields */ }Expand description
A templated field.
In many cases, components can be configured so that part of the component’s functionality can be customized on a per-event basis. For example, you have a sink that writes events to a file and you want to specify which file an event should go to by using an event field as part of the input to the filename used.
By using Template, users can specify either fixed strings or templated strings. Templated strings use a common syntax to
refer to fields in an event that is used as the input data when rendering the template. An example of a fixed string
is my-file.log. An example of a template string is my-file-{{key}}.log, where {{key}}
is the key’s value when the template is rendered into a string.
