Struct ResourceValidator

pub struct ResourceValidator;

Resource validator for P2M requests.

This validator ensures that incoming Process-to-Middleware requests reference valid, accessible system resources before they are processed by the core services. It performs system-level validation that cannot be done at the type level.

Validation Rules

• Process IDs: Must correspond to currently running processes
• Socket Addresses: Must be parseable and use compatible address families
• File Descriptors: Accepted without validation (OS handles validity)

Usage

The validator methods are called by the P2M service when resource validation is enabled through the with_resource_validation(true) builder method.

Implementations

impl ResourceValidator

pub fn is_valid_process(&self, pid: i32) -> bool

Validates that a process ID corresponds to a currently running process.

Queries the system process table to verify that the specified PID is associated with an active process. This prevents operations on stale or invalid process identifiers.

Arguments

• pid - Process identifier to validate

Returns

true if the process exists and is accessible, false otherwise

pub fn is_valid_stream(&self, local_socket: &str, peer_socket: &str) -> bool

Validates that socket addresses are well-formed and compatible.

Ensures that both local and peer socket addresses can be parsed and use compatible address families (both IPv4 or both IPv6). This prevents network operations with mismatched or invalid addresses.

Arguments

• local_socket - Local socket address string
• peer_socket - Peer socket address string

Returns

true if both addresses are valid and compatible, false otherwise
