Struct ErrorContext 

pub struct ErrorContext {
    pub location: Option<String>,
    pub thread_id: Option<ThreadId>,
    pub timestamp: SystemTime,
    pub node_id: Option<NodeId>,
    pub port_id: Option<String>,
    pub parameter_id: Option<String>,
    pub extras: Vec<(String, String)>,
}

Additional context for errors

This can be attached to errors to provide more information about where and why they occurred.

Fields

location: Option<String>

Node ID (if applicable)

port_id: Option<String>

Port ID (if applicable)

parameter_id: Option<String>

Parameter ID (if applicable)

extras: Vec<(String, String)>

Additional key-value pairs
