Struct InputEntryFunctionData 

pub struct InputEntryFunctionData { /* private fields */ }

A type-safe builder for entry function payloads.

This builder provides an ergonomic way to construct entry function calls with automatic BCS encoding of arguments.

Example

use aptos_sdk::transaction::InputEntryFunctionData;
use aptos_sdk::types::AccountAddress;

let payload = InputEntryFunctionData::new("0x1::aptos_account::transfer")
    .arg(AccountAddress::from_hex("0x123").unwrap())
    .arg(1_000_000u64)  // 0.01 APT in octas
    .build()?;

Implementations

impl InputEntryFunctionData

pub fn new(function_id: &str) -> InputEntryFunctionDataBuilder

Creates a new entry function data builder.

Arguments

• function_id - The full function identifier (e.g., “0x1::coin::transfer”)

Example

let builder = InputEntryFunctionData::new("0x1::aptos_account::transfer");

pub fn from_parts( module: MoveModuleId, function: impl Into<String>, ) -> InputEntryFunctionDataBuilder

Creates a builder from module and function name.

Arguments

• module - The module ID
• function - The function name

pub fn transfer_apt( recipient: AccountAddress, amount: u64, ) -> AptosResult<TransactionPayload>

Builds an APT transfer payload.

Arguments

• recipient - The recipient address
• amount - Amount in octas (1 APT = 10^8 octas)

Example

let payload = InputEntryFunctionData::transfer_apt(recipient, 1_000_000)?;

Errors

Returns an error if the function ID is invalid or if BCS encoding of arguments fails.

pub fn transfer_coin( coin_type: &str, recipient: AccountAddress, amount: u64, ) -> AptosResult<TransactionPayload>

Builds a coin transfer payload for any coin type.

Arguments

• coin_type - The coin type (e.g., “0x1::aptos_coin::AptosCoin”)
• recipient - The recipient address
• amount - Amount in the coin’s smallest unit

Errors

Returns an error if the function ID is invalid, the coin type is invalid, or if BCS encoding of arguments fails.

pub fn create_account( auth_key: AccountAddress, ) -> AptosResult<TransactionPayload>

Builds an account creation payload.

Arguments

• auth_key - The authentication key (32 bytes)

Errors

Returns an error if the function ID is invalid or if BCS encoding of arguments fails.

pub fn rotate_authentication_key( from_scheme: u8, from_public_key_bytes: Vec<u8>, to_scheme: u8, to_public_key_bytes: Vec<u8>, cap_rotate_key: Vec<u8>, cap_update_table: Vec<u8>, ) -> AptosResult<TransactionPayload>

Builds a payload to rotate an account’s authentication key.

Arguments

• Various rotation parameters

Errors

Returns an error if the function ID is invalid or if BCS encoding of arguments fails.

pub fn register_coin(coin_type: &str) -> AptosResult<TransactionPayload>

Builds a payload to register a coin store.

Arguments

• coin_type - The coin type to register

Errors

Returns an error if the function ID is invalid, the coin type is invalid, or if building the payload fails.

pub fn publish_package( metadata_serialized: Vec<u8>, code: Vec<Vec<u8>>, ) -> AptosResult<TransactionPayload>

Builds a payload to publish a module.

Arguments

• metadata_serialized - Serialized module metadata
• code - Vector of module bytecode

Errors

Returns an error if the function ID is invalid or if BCS encoding of arguments fails.
