Struct Memory

pub struct Memory {
    config: MemoryConfig,
}

The main struct for the memory monitoring thread.

An instance of this struct contains the configuration and the state required to perform periodic memory checks.

Fields

config: MemoryConfig

configuration read from .toml file

Implementations

impl Memory

pub fn new(config: MemoryConfig) -> Result<Memory, MemoryConfigError>

Creates a new Memory instance.

Stores the configuration and initializes the lock flags.

Arguments

• config - A reference to the global ConfigData containing the memory configuration.

Returns

A new Memory instance wrapped in a Result type ready to be executed in its own thread.

pub fn execute(&mut self, memory_channels: &mut MemoryChannels)

Starts the memory monitoring loop.

1. Checks for a Quit command from the signal handler to terminate gracefully.
2. Checks the current resident and allocated memory usage against configured limits.
3. Logs a warning if any limit is exceeded.
4. Sleeps for the configured interval before the next check.

Arguments

• memory_channels - A mutable reference to the channels used for receiving shutdown commands.

Trait Implementations

impl ProcessExternalRequestTrait for Memory

fn process_external_request( &mut self, rx_from_signal_handler: &mut AquaReceiver<InternalCommand>, _: Option<&mut AquaReceiver<InternalCommand>>, ) -> (bool, bool, bool)

Checks for and processes new commands relevant to the Memory module from external channels.

This is the specialized implementation of ProcessExternalRequestTrait for TcpCommunication. It delegates directly to process_external_request_without_messaging, indicating that the Memory module primarily processes commands from the signal handler and does not use a separate messaging channel for external requests.

Arguments

• rx_from_memory - A reference to the receiver end of the channel for commands originating from the signal handler.
• _ - This parameter is ignored, as the Memory module does not process messages from a messaging channel in this context.

Returns

A tuple (bool, bool, bool) indicating the status of commands received:

• The first bool is true if a Quit command was received; otherwise false.
• The second bool is always false (no “Start” commands processed).
• The third bool is always false (no “Stop” commands processed).
