Function dynamic_redaction

pub fn dynamic_redaction<I, F>(func: F) -> Redaction
where
    I: Into<Content>,
    F: Fn(Content, ContentPath<'_>) -> I + Send + Sync + 'static,

Creates a dynamic redaction.

This can be used to redact a value with a different value but instead of statically declaring it a dynamic value can be computed. This can also be used to perform assertions before replacing the value.

The closure is passed two arguments: the value as Content and the path that was selected (as ContentPath)

Example:

settings.add_redaction(".id", dynamic_redaction(|value, path| {
    assert_eq!(path.to_string(), ".id");
    assert_eq!(
        value
            .as_str()
            .unwrap()
            .chars()
            .filter(|&c| c == '-')
            .count(),
        4
    );
    "[uuid]"
}));
