Substrate for cellular automata in Rust. Named after the LB medium used in mircobiology. Also look into Angelina Fanny Hesse ;) The underlying grid is of toroidal shape, i.e. the coordinate values/neighbours wrap around. This code is dual-licensed under the MIT/Apache 2.0 licenses.

examples

• retrieve value as grid: cargo run --example retrieval
• implementation of rule 30: cargo run --example rule30
• save grid states as JSON: cargo run --example json

features

dead-alive-only

Enable utility functions for binary (only) cell state.

dead-alive-into-bool

Allow dead/alive cell to be converted into boolean values.

dead-alive-u8-utils

Group 8 binary cell states into an octet for nicer processing and i/o.

versions / changes

upcoming

1.2

• documentation extended
• minor code cleaning
• rule30 example minimised
• fixed signature of cs8_into_u8() to be internally compatible
• added u8_into_cs8 utility function
• grouped CellState / u8 conversions under feature "dead-alive-u8-utils"
  • dropped feature "dead-alive-into-group-u8"
• added JSON example
• implemented next() as iterator
• implemented next_byte() for easier byte conversion

1.1

• binary cell states are explicit feature now: "dead-alive-only"
• optional conversion of binary cell states into boolean value as feature: "dead-alive-into-bool"
• convert eight cellstates into an u8 (octet) via feature: "dead-alive-into-group-u8"

1.0

• grid works (setting & retrieving cell states)
• universe implemented (rules via function pointer)
• tests
• examples
• documentation
