Implementations§

Source§

impl SolanaTokenProgram

Source

pub async fn get_token_program_for_mint<P: SolanaProviderTrait>( provider: &P, mint: &Pubkey, ) -> Result<Pubkey, TokenError>

Get the token program for a mint

Source

pub fn is_token_program(program_id: &Pubkey) -> bool

Checks if a program ID corresponds to a known token program.

§Arguments
  • program_id - The program ID to check
§Returns

true if the program ID is SPL Token or Token-2022, false otherwise

Source

pub fn create_transfer_checked_instruction( program_id: &Pubkey, source: &Pubkey, mint: &Pubkey, destination: &Pubkey, authority: &Pubkey, amount: u64, decimals: u8, ) -> Result<Instruction, TokenError>

Creates a transfer checked instruction.

§Arguments
  • program_id - The program ID of the token program
  • source - The source token account
  • mint - The mint address
  • destination - The destination token account
  • authority - The authority that can sign for the source account
  • amount - The amount to transfer
  • decimals - The number of decimals for the token
§Returns

A Result containing either the transfer instruction or a TokenError

Source

pub fn unpack_account( program_id: &Pubkey, account: &SolanaAccount, ) -> Result<TokenAccount, TokenError>

Unpacks a Solana account into a TokenAccount structure.

§Arguments
  • program_id - The program ID of the token program
  • account - The Solana account to unpack
§Returns

A Result containing either the unpacked TokenAccount or a TokenError

Source

pub fn get_associated_token_address( program_id: &Pubkey, wallet: &Pubkey, mint: &Pubkey, ) -> Pubkey

Gets the associated token address for a wallet and mint.

§Arguments
  • program_id - The program ID of the token program
  • wallet - The wallet address
  • mint - The mint address
§Returns

The associated token address

Source

pub fn create_associated_token_account( program_id: &Pubkey, payer: &Pubkey, wallet: &Pubkey, mint: &Pubkey, ) -> Instruction

Creates an instruction to create an associated token account.

§Arguments
  • program_id - The program ID of the token program
  • payer - The account that will pay for the account creation
  • wallet - The wallet address
  • mint - The mint address
§Returns

An instruction to create the associated token account

Source

pub fn unpack_instruction( program_id: &Pubkey, data: &[u8], ) -> Result<TokenInstruction, TokenError>

Unpacks a token instruction from its binary data.

§Arguments
  • program_id - The program ID of the token program
  • data - The binary instruction data
§Returns

A Result containing either the unpacked TokenInstruction or a TokenError

Source

pub async fn get_and_unpack_token_account<P: SolanaProviderTrait>( provider: &P, owner: &Pubkey, mint: &Pubkey, ) -> Result<TokenAccount, TokenError>

Gets a token account for a given owner and mint, then unpacks it into a TokenAccount struct.

This is a convenience method that combines several operations:

  1. Finds the appropriate token program for the mint
  2. Derives the associated token account address
  3. Fetches the account data
  4. Unpacks it into a structured TokenAccount
§Arguments
  • provider - The Solana provider to use for RPC calls
  • owner - The public key of the token owner
  • mint - The public key of the token mint
§Returns

A Result containing the unpacked TokenAccount or a TokenError
