Struct Process 

pub struct Process;

Utilities for managing process-level operations.

Implementations

impl Process

pub fn args() -> Vec<String>

Returns a vector of command-line arguments passed to the program.

Examples

use seda_sdk_rs::process::Process;

let args = Process::args();
// args[0] is the program name
// args[1] would be the first argument

pub fn envs() -> BTreeMap<String, String>

Returns a map of all environment variables.

Examples

use seda_sdk_rs::process::Process;

std::env::set_var("TEST_VAR", "test_value");

let env_vars = Process::envs();
assert!(env_vars.contains_key("TEST_VAR"));
for (key, value) in env_vars {
    println!("{}: {}", key, value);
}

pub fn get_inputs() -> Vec<u8>

Retrieves and decodes the data request inputs

Panics

This function will panic if:

• There were no arguments passed to the program.
• The second argument (index 1) is not a valid hex string.

Examples

use seda_sdk_rs::process::Process;

let input_bytes = Process::get_inputs();
// Process the input bytes...

pub fn is_tally_vm_mode() -> bool

Checks if the current VM mode is set to tally mode.

Examples

use seda_sdk_rs::process::Process;

std::env::set_var("VM_MODE", "tally");
if Process::is_tally_vm_mode() {
    // Handle tally mode specific logic
}

pub fn is_dr_vm_mode() -> bool

Checks if the current VM mode is set to DR mode.

Examples

use seda_sdk_rs::process::Process;

if Process::is_dr_vm_mode() {
    let replication = Process::replication_factor();
    // Handle DR mode specific logic
}

pub fn success(result: &[u8]) -> !

Exits the process successfully (code 0) with the given result.

Examples

use seda_sdk_rs::process::Process;

let result = vec![0x01, 0x02, 0x03];
Process::success(&result);

pub fn error(result: &[u8]) -> !

Exits the process with an error (code 1) and the given result.

Examples

use seda_sdk_rs::process::Process;

let error_data = vec![0xFF];
Process::error(&error_data);

pub fn replication_factor() -> u16

Gets the replication factor for the data request

Panics

This function will panic if:

• The DR_REPLICATION_FACTOR_ENV_KEY environment variable is not set.
• The value of DR_REPLICATION_FACTOR_ENV_KEY is not a valid u16.

These conditions should never happen in a properly configured environment.

Examples

use seda_sdk_rs::process::Process;

if Process::is_dr_vm_mode() {
    let factor = Process::replication_factor();
    println!("Replication factor: {}", factor);
}

pub fn exit_with_message(code: u8, message: &str) -> !

Exits the process with the given code and message.

Examples

use seda_sdk_rs::process::Process;

// Exit with an error message
Process::exit_with_message(1, "Operation failed: invalid input");

// Exit with success message
Process::exit_with_message(0, "Operation completed successfully");

pub fn exit_with_result(code: u8, result: &[u8]) -> !

Exits the process with the given code and result bytes.

Examples

use seda_sdk_rs::process::Process;

let result = vec![1, 2, 3, 4];
Process::exit_with_result(0, &result);

pub fn exit(code: u8) -> !

Exits the process with the given code and an empty result.

Examples

use seda_sdk_rs::process::Process;

// Exit successfully with no result
Process::exit(0);

// Exit with error code
Process::exit(1);
