Struct PatternLine 

pub struct PatternLine { /* private fields */ }

Helper struct that permits to transform a template line with patterns into an instantiated line from a match.

Useful when you permit the user to reconstruct lines from an action, like in reaction’s native actions and in the virtual plugin:

actions:
  native:
    cmd: ["iptables", "...", "<ip>"]

  virtual:
    type: virtual
    options:
      send: "<ip>: bad password on user <user>"
      to: "my_virtual_stream"

Usage example:

let template = "<ip>: bad password on user <user>".to_string();
let patterns = vec!["ip".to_string(), "user".to_string()];
let pattern_line = PatternLine::new(template, patterns);

assert_eq!(
  pattern_line.line(vec!["1.2.3.4".to_string(), "root".to_string()]),
  "1.2.3.4: bad password on user root".to_string(),
);

You can find full examples in those plugins: reaction-plugin-virtual, reaction-plugin-cluster.

Implementations

impl PatternLine

pub fn new(template: String, patterns: Vec<String>) -> Self

Construct PatternLine from a template line and the list of patterns of the underlying Filter.

This list of patterns comes from super::ActionConfig.

pub fn line(&self, match_: Vec<String>) -> String

Trait Implementations

impl Debug for PatternLine

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
