Struct ReconnectionConfig 

pub struct ReconnectionConfig {
    pub enabled: bool,
    pub max_attempts: u32,
    pub initial_delay: Duration,
    pub max_delay: Duration,
}

Reconnection configuration

Controls automatic reconnection behavior after connection drops.

Construct via the derived ReconnectionConfig::builder (no validation, fields default to the DEFAULT_* constants) or via the validating positional constructor ReconnectionConfig::new.

enabled defaults to true in 0.4.0 — Rust users now get the production-safe behaviour out of the box, aligning with reqwest / redis-rs / tokio-tungstenite ergonomics. Bindings that need to preserve the historical “no auto-reconnect” semantics of fugle-marketdata-{python,node} SDKs MUST construct ReconnectionConfig::disabled explicitly at the FFI boundary.

Fields

enabled: bool

Whether auto-reconnect is active. When false, ReconnectionManager::should_reconnect always returns false regardless of the close code.

max_attempts: u32

Maximum reconnection attempts before giving up

initial_delay: Duration

Initial delay before first reconnection attempt

max_delay: Duration

Maximum delay between reconnection attempts

Implementations

impl ReconnectionConfig

pub fn builder() -> ReconnectionConfigBuilder

Create an instance of ReconnectionConfig using the builder syntax

impl ReconnectionConfig

pub fn new( max_attempts: u32, initial_delay: Duration, max_delay: Duration, ) -> Result<ReconnectionConfig, MarketDataError>

Create a new reconnection config with validation

Errors

Returns MarketDataError::ConfigError if:

• max_attempts is 0 (must be >= 1)
• initial_delay is less than 100ms
• max_delay is less than initial_delay

Constructing via new() is treated as explicit opt-in, so the returned config has enabled: true. To get a disabled config (e.g. to fall back to “no reconnect at all”) use ReconnectionConfig::disabled or ReconnectionConfig::default().

Errors

Returns MarketDataError on transport, protocol, deserialization, validation, or peer-initiated failures.

pub fn disabled() -> ReconnectionConfig

Build an explicitly disabled reconnection config.

should_reconnect() will always return false regardless of close code.

Stability

Stable public API. FFI binding crates (fugle-marketdata-py, fugle-marketdata-js, fugle-marketdata-uniffi) call this at the FFI boundary to preserve their historical “no auto-reconnect” semantics — see the tests/reconnect_default.rs workspace-level gate. The function’s name and signature will be preserved across every 0.x release; downstream code can rely on it.
