Struct DependencyState 

pub struct DependencyState { /* private fields */ }

Dependency State: Resource relationship graph

Implementations

impl DependencyState

pub fn new() -> Self

Create a new empty dependency state.

pub async fn add_dependency(&self, from: &str, to: &str, edge: DependencyEdge)

Add a dependency between resources

For a “BlockedBy” relationship: add_dependency("op-a", "op-b", BlockedBy) means “op-a is blocked by op-b”, so op-b must execute before op-a. The edge direction is from→to (to comes before from in execution order).

pub async fn remove_dependency(&self, from: &str, to: &str)

Remove a dependency

pub async fn would_deadlock(&self, agent_id: &str, resources: &[String]) -> bool

Check if acquiring resources would create a deadlock

pub async fn get_blocking_resources(&self, resource_id: &str) -> Vec<String>

Get all resources that must be released before agent can acquire resource

pub async fn set_holder(&self, resource_id: &str, agent_id: Option<&str>)

Set the current holder of a resource

pub async fn get_current_holders(&self) -> HashMap<String, String>

Get current resource holders

pub async fn get_agent_resources(&self, agent_id: &str) -> Vec<String>

Get resources held by an agent

pub async fn get_execution_order(&self, operation_ids: &[String]) -> Vec<String>

Topological sort of operations respecting dependencies

Trait Implementations

impl Default for DependencyState

fn default() -> Self

Returns the “default value” for a type.
