Struct SimConfig 

pub struct SimConfig { /* private fields */ }

Configuration for a simulation run.

TigerStyle:

• Immutable after creation
• Seed logged for reproducibility
• All limits explicit

Implementations

impl SimConfig

pub fn with_seed(seed: u64) -> Self

Create config with explicit seed.

Panics

Never panics - all u64 values are valid seeds.

Example

use umi_memory::dst::SimConfig;
let config = SimConfig::with_seed(12345);
assert_eq!(config.seed(), 12345);

pub fn from_env_or_random() -> Self

Create config from DST_SEED env var or random.

If DST_SEED is set, uses that value. Otherwise, generates a random seed and prints it for reproducibility.

Example

use umi_memory::dst::SimConfig;
// Set DST_SEED=42 to get deterministic seed
let config = SimConfig::from_env_or_random();

pub fn seed(&self) -> u64

Get the seed.

pub fn steps_max(&self) -> u64

Get the maximum number of steps.

pub fn with_steps_max(self, steps_max: u64) -> Self

Create a new config with a different steps_max.
