Android System Properties for Linux and Android both.

This crate provides a way to access system properties on Linux and Android.

Features

• Set system properties.
• Wait for system properties.
• Serialize system properties.
• Deserialize system properties.

Usage

#[cfg(target_os = "android")]
{
    use rsproperties::{init, PropertyConfig};
    use std::path::PathBuf;

    // Initialize with defaults
    rsproperties::init(None);

    // Initialize with custom directories
    let config = PropertyConfig {
        properties_dir: Some(PathBuf::from("/custom/properties")),
        socket_dir: Some(PathBuf::from("/custom/socket")),
    };
    rsproperties::init(config);

    // Get a value of the property.
    let value = rsproperties::get_with_default("ro.build.version.sdk", "0");
    println!("ro.build.version.sdk: {}", value);

    // Set a value of the property.
    rsproperties::set("test.property", "test.value").unwrap();
}

Functions

get

Get a value of the property. If the property is not found, it returns an empty string. If an error occurs, it returns Err.

get_with_default

Get a value of the property. If the property is not found, it returns the default value. If an error occurs, it returns the default value.

get_with_result

init

Initialize system properties with flexible configuration options.

properties_dir

Get the system properties directory. Returns the configured directory if init() was called, otherwise returns the default PROP_DIRNAME (/dev/properties).

set

Set a value of the property. If an error occurs, it returns Err. It uses socket communication to set the property. Because it is designed for client applications,

socket_dir

Get the current socket directory. Returns the configured socket directory, environment variable, or default.

system_properties

Get the system properties. Before calling this function, init() must be called. It panics if init() is not called or the system properties cannot be opened.
