# `Milvex.Backoff`

Exponential backoff calculator with jitter support.

Provides delay calculation for connection retry logic to prevent
thundering herd problems when multiple clients reconnect simultaneously.

# `calculate`

```elixir
@spec calculate(
  non_neg_integer(),
  pos_integer(),
  pos_integer(),
  float(),
  float()
) :: pos_integer()
```

Calculates the next delay using exponential backoff with optional jitter.

The formula is: `min(base_delay * multiplier^attempt, max_delay) +/- jitter`

## Parameters

  - `attempt` - Current retry attempt number (0-based, first retry is attempt 0)
  - `base_delay` - Base delay in milliseconds
  - `max_delay` - Maximum delay cap in milliseconds
  - `multiplier` - Exponential multiplier (default: 2.0)
  - `jitter` - Jitter factor 0.0-1.0 (default: 0.1)

## Examples

    iex> Milvex.Backoff.calculate(0, 1000, 60000, 2.0, 0.0)
    1000

    iex> Milvex.Backoff.calculate(3, 1000, 60000, 2.0, 0.0)
    8000

    iex> Milvex.Backoff.calculate(10, 1000, 60000, 2.0, 0.0)
    60000
