hopr_strategy/
lib.rs

1//! This crate contains all the Strategies for HOPRd.
2//! Strategies are vital for (partial) automation of ticket and HOPR channel operations
3//! during node runtime.
4//!
5//! - [passive strategy](crate::strategy::MultiStrategy)
6//! - [promiscuous strategy](crate::promiscuous)
7//! - [auto funding strategy](crate::auto_funding)
8//! - [auto redeeming strategy](crate::auto_redeeming)
9//! - [aggregating strategy](crate::aggregating)
10//! - [multiple strategy chains](crate::strategy)
11//!
12//! HOPRd can be configured to use any of the above strategies.
13//!
14//! ## Configuring strategies in HOPRd
15//!
16//! There are two ways of configuring strategies in HOPRd: via CLI and via a YAML config file.
17//!
18//! The configuration through CLI allows only fairly primitive single-strategy setting, through the `defaultStrategy`
19//! parameter. It can be set to any of the above strategies, however, the strategy parameters are not further
20//! configurable via the CLI and will always have their default values.
21//! In addition, if the ` disableTicketAutoRedeem ` CLI argument is `false`, the default Auto Redeem strategy is added
22//! to the strategy configured via the `defaultStrategy` argument (they execute together as Multi strategy).
23//!
24//! For more complex strategy configurations, the YAML configuration method is recommended via the `strategy` YAML
25//! section. In this case, the top-most strategy is always assumed to be Multi strategy:
26//!
27//! ```yaml
28//! strategy:
29//!   on_fail_continue: true
30//!   allow_recursive: true
31//!   execution_interval: 60
32//!   strategies:
33//!     - !Promiscuous
34//!       max_channels: 50
35//!       new_channel_stake: 20
36//!     - !AutoFunding
37//!       funding_amount: 20
38//!     - !Aggregating:
39//!       aggregation_threshold: 1000
40//! ```
