Struct PathMap 

pub struct PathMap(/* private fields */);

Path mapping for conditional edges

Maps router return values to target node names. Used for validation and graph visualization.

Examples

use juncture_core::edge::PathMap;
use std::collections::HashMap;

// From HashMap
let mut map = HashMap::new();
map.insert("approve".to_string(), "publish".to_string());
map.insert("reject".to_string(), "archive".to_string());
let path_map = PathMap::from(map);

// From slice
let path_map = PathMap::from(&[("approve", "publish"), ("reject", "archive")][..]);

Implementations

impl PathMap

pub fn new() -> Self

Create a new empty path map

pub fn insert(&mut self, key: impl Into<String>, value: impl Into<String>)

Add a path mapping

pub fn get(&self, key: &str) -> Option<&String>

Get the target for a given route value

pub fn contains_key(&self, key: &str) -> bool

Check if the map contains a key

pub fn iter(&self) -> impl Iterator<Item = (&String, &String)>

Get an iterator over all mappings

pub fn len(&self) -> usize

Get the number of mappings

pub fn is_empty(&self) -> bool

Check if the map is empty

Trait Implementations

impl Clone for PathMap

fn clone(&self) -> PathMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PathMap

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

Formats the value using the given formatter.

impl Default for PathMap

fn default() -> PathMap

Returns the “default value” for a type.

impl From<&[(&str, &str)]> for PathMap

fn from(pairs: &[(&str, &str)]) -> Self

Converts to this type from the input type.

impl<const N: usize> From<&[(&str, &str); N]> for PathMap

fn from(pairs: &[(&str, &str); N]) -> Self

Converts to this type from the input type.

impl From<HashMap<String, String>> for PathMap

fn from(map: HashMap<String, String>) -> Self

Converts to this type from the input type.

impl PartialEq for PathMap

fn eq(&self, other: &PathMap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
