Enum FlowControlMode 

pub enum FlowControlMode {
    FailClosed,
    FailOpen,
    WaitAndRetry,
}

Flow control behavior when an agent signals it cannot accept requests.

When an agent sends a flow control “pause” signal, this determines whether requests should fail immediately or be allowed through.

Variants

FailClosed

Fail requests when agent is paused (default, safer).

Returns AgentProtocolError::FlowControlPaused immediately. Use this when you want strict backpressure and can handle the error at the caller (e.g., return 503 to client).

FailOpen

Allow requests through even when agent is paused.

Requests proceed without agent processing. Use this when agent processing is optional (e.g., logging, analytics) and you prefer availability over consistency.

WaitAndRetry

Queue requests briefly, then fail if still paused.

Waits up to flow_control_wait_timeout for the agent to resume before failing. Useful for transient pauses.

Trait Implementations

impl Clone for FlowControlMode

fn clone(&self) -> FlowControlMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlowControlMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FlowControlMode

fn default() -> FlowControlMode

Returns the “default value” for a type.

impl PartialEq for FlowControlMode

fn eq(&self, other: &FlowControlMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
