Struct rain::Graph

pub struct Graph<V> { /* fields omitted */ }

The graph drawing structure

Methods

impl<V> Graph<V> where V: Clone + Default + Ord + PartialEq + Debug,
        f64: From<V>

fn new() -> Self

Create a new Graph for drawing

Example

use rain::Graph;

let _ :Graph<u8> = Graph::new();

fn with_prefix_length(length: usize) -> Self

Create a new Graph for drawing with a custom length of the identifier (prefix)

Example

use rain::Graph;

let _ :Graph<u8> = Graph::with_prefix_length(25);

fn set_log_level(self, level: LogLevel) -> Self

Set the global log level for reporting

fn add<T>(&mut self, identifier: T, value: V) -> RainResult<T> where T: Display

Add a data value to the graph by some identifier which can be displayed somehow.

Example

use rain::Graph;

let mut graph = Graph::new();
let line = graph.add("Line 1", 0).unwrap();

assert_eq!(line, "Line 1");

fn remove<T>(&mut self, identifier: T) -> RainResult<T> where T: Display

Remove a line from the graph

Example

use rain::Graph;

let mut graph = Graph::new();
let line = graph.add("Line 1", 0).unwrap();

let removed_line = graph.remove(line).unwrap();
assert_eq!(removed_line, "Line 1");

fn print(&mut self) -> RainResult<()>

Prints the graph

Example

use rain::Graph;

let mut graph = Graph::new();

assert!(graph.add("Line 1", 0).is_ok());
assert!(graph.add("Line 2", 0).is_ok());

graph.print();

fn print_if_new_data(&mut self) -> RainResult<bool>

Print only if new data is available. Returns an indicator if somethings was printed or not.

Example

use rain::Graph;

let mut graph = Graph::new();

assert!(graph.add("Line 1", 0).is_ok());
assert!(graph.add("Line 2", 0).is_ok());

graph.print_if_new_data();
graph.print_if_new_data();
