Struct TransitionMatrix 

pub struct TransitionMatrix<S: States, const NS: usize, const NE: usize>(/* private fields */);

A matrix of state transitions.

This structure organizes transitions in a 2D matrix where:

• Rows represent source states (indexed by state index)
• Columns represent events (indexed by event index)
• Each cell contains the destination state for that state-event pair

The matrix allows O(1) lookup of the next state given a current state and event.

Type Parameters

• S: The state type implementing States
• NS: The number of states (rows)
• NE: The number of events (columns)

Implementations

impl<S: States, const NS: usize, const NE: usize> TransitionMatrix<S, NS, NE>

pub const fn new(arr: [[Transition<S>; NE]; NS]) -> Self

Creates a new transition matrix from a 2D array.

Example

use tinystate::{TransitionMatrix, Transition};

let matrix = TransitionMatrix::new([[Transition::new(MyState::A); 1]; 1]);
