Detailed Description

Configuration for filesystem-based IPC communication.

This configuration defines how the physiology system should use filesystem operations to communicate between Edge and Core components.

Member Function Documentation

FromJson()

absl::StatusOr< FileIpcConfiguration > presage::smartspectra::file_ipc::FileIpcConfiguration::FromJson ( const nlohmann::json & j )

static

Create a configuration from a JSON object.

Parameters

j	The JSON object to deserialize

Returns

FileIpcConfiguration created from the JSON or error status

LoadFromJson()

absl::StatusOr< FileIpcConfiguration > presage::smartspectra::file_ipc::FileIpcConfiguration::LoadFromJson ( const std::filesystem::path & path )

static

Load configuration from a JSON file.

Parameters

path	Path to the JSON configuration file

Returns

Loaded configuration (with defaults for missing fields) or error status

SaveToJson()

absl::Status presage::smartspectra::file_ipc::FileIpcConfiguration::SaveToJson ( const FileIpcConfiguration & config, const std::filesystem::path & path )

static

Save configuration to a JSON file.

Parameters

config	The configuration to save
path	Path where the JSON file should be written

Returns

OK status or error status

ToJson()

nlohmann::json presage::smartspectra::file_ipc::FileIpcConfiguration::ToJson ( ) const

nodiscard

Convert this configuration to a JSON object.

Returns

nlohmann::json representation of this configuration

Member Data Documentation

base_directory

std::filesystem::path presage::smartspectra::file_ipc::FileIpcConfiguration::base_directory = "/tmp/physiology_ipc"

Base directory for all IPC files. This directory will contain:

• core_metrics.jsonl: Stream of Core metrics (MetricsBuffer messages)
• edge_metrics.jsonl: Stream of Edge metrics (Metrics messages)
• status_codes.jsonl: Stream of status updates (StatusValue messages)
• frames/: Directory containing video frames with timestamps
• recording_state.json: Current recording state
• recording_command.json: Commands to control recording

compress_frames

bool presage::smartspectra::file_ipc::FileIpcConfiguration::compress_frames = false

Whether to compress frame data before writing. Default: false (frames are expected to be already compressed)

create_if_missing

bool presage::smartspectra::file_ipc::FileIpcConfiguration::create_if_missing = true

Whether to create the base directory if it doesn't exist. Default: true

enable_debug_logging

bool presage::smartspectra::file_ipc::FileIpcConfiguration::enable_debug_logging = false

Whether to enable debug logging for IPC operations. Default: false

io_buffer_size

size_t presage::smartspectra::file_ipc::FileIpcConfiguration::io_buffer_size = 8192

Buffer size for file I/O operations. Default: 8192 bytes

jpeg_quality

int presage::smartspectra::file_ipc::FileIpcConfiguration::jpeg_quality = 85

JPEG compression quality level for frame files (1-100). Higher values mean better quality but larger file sizes. Default: 85

max_frame_count

size_t presage::smartspectra::file_ipc::FileIpcConfiguration::max_frame_count = 1000

Maximum number of frames to keep in the frames directory. Older frames will be deleted when this limit is exceeded. Default: 1000 frames (0 = unlimited)

truncate_on_init

bool presage::smartspectra::file_ipc::FileIpcConfiguration::truncate_on_init = false

Whether to truncate existing files on initialization. Default: false (append to existing files)

use_file_locking

bool presage::smartspectra::file_ipc::FileIpcConfiguration::use_file_locking = true

Whether to use file locking for concurrent access safety. Default: true
