Overview

Instruction for initializing a new token account.

This instruction is used to initialize a new token account for a given mint and owner. It is used in conjunction with the CreateAccount instruction to create and initialize a new token account. Note that the AssociatedTokenAccount::CreateAssociatedTokenAccountInstruction is a special “all-in-one” instruction that creates and initializes the account in a single instruction.

Examples:

Build an InitializeAccount instruction

instruction = Solace::Instructions::SplToken::InitializeAccountInstruction.build(
  account_index: 0,
  mint_index: 1,
  owner_index: 2,
  rent_sysvar_index: 3,
  program_index: 4
)
