Struct respo::StatesTree

pub struct StatesTree {
    pub data: MaybeState,
    pub cursor: Vec<String>,
    pub branches: HashMap<String, Box<StatesTree>>,
}

Respo maintains states in a tree structure, where the keys are strings, each child component “picks” a key to attach its own state to the tree, and it dispatches events to global store to update the state.

Fields

data: MaybeState

local data

cursor: Vec<String>

the path to the current state in the tree, use in updating

branches: HashMap<String, Box<StatesTree>>

holding children states

Implementations

impl StatesTree

pub fn path(&self) -> Vec<String>

get cursor

pub fn pick(&self, name: &str) -> StatesTree

pick a child branch as new cursor

pub fn set_in_mut(&mut self, path: &[String], new_state: MaybeState)

in-place mutation of state tree

Trait Implementations

impl Clone for StatesTree

fn clone(&self) -> StatesTree

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StatesTree

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

Formats the value using the given formatter.

impl Default for StatesTree

fn default() -> StatesTree

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StatesTree

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<StatesTree> for StatesTree

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for StatesTree

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
