Struct TokenExtensionsProgram 

pub struct TokenExtensionsProgram<'a>(/* private fields */);

Wrapper for Program for the SPL Token Extensions program.

Methods from Deref<Target = NoStdAccountInfo>

pub fn to_info_c(&self) -> AccountInfoC

CPI utility function

pub fn to_meta_c(&self) -> AccountMetaC

CPI utility function

pub fn to_meta_c_signer(&self) -> AccountMetaC

CPI utility function.

Intended for pdas that did not sign transaction but need to sign for cpi.

pub fn key(&self) -> &Pubkey

pub fn owner(&self) -> &Pubkey

pub fn is_signer(&self) -> bool

pub fn is_writable(&self) -> bool

pub fn executable(&self) -> bool

pub fn data_len(&self) -> usize

pub unsafe fn unchecked_borrow_lamports(&self) -> &u64

Safety

This does not check or modify the 4-bit refcell. Useful when instruction has verified non-duplicate accounts.

pub unsafe fn unchecked_borrow_mut_lamports(&self) -> &mut u64

Safety

This does not check or modify the 4-bit refcell. Useful when instruction has verified non-duplicate accounts.

pub unsafe fn unchecked_borrow_data(&self) -> &[u8]

Safety

This does not check or modify the 4-bit refcell. Useful when instruction has verified non-duplicate accounts.

pub unsafe fn unchecked_borrow_mut_data(&self) -> &mut [u8]

Safety

This does not check or modify the 4-bit refcell. Useful when instruction has verified non-duplicate accounts.

pub fn try_borrow_lamports(&self) -> Result<Ref<'_, u64>, ProgramError>

Tries to get a read only reference to the lamport field, failing if the field is already mutable borrowed or if 7 borrows already exist.

pub fn try_borrow_mut_lamports(&self) -> Result<RefMut<'_, u64>, ProgramError>

Tries to get a read only reference to the lamport field, failing if the field is already borrowed in any form.

pub fn try_borrow_data(&self) -> Result<Ref<'_, [u8]>, ProgramError>

Tries to get a read only reference to the data field, failing if the field is already mutable borrowed or if 7 borrows already exist.

pub fn try_borrow_mut_data(&self) -> Result<RefMut<'_, [u8]>, ProgramError>

Tries to get a read only reference to the data field, failing if the field is already borrowed in any form.

pub fn realloc( &self, new_len: usize, zero_init: bool, ) -> Result<(), ProgramError>

Realloc the account’s data and optionally zero-initialize the new memory.

Note: Account data can be increased within a single call by up to solana_program::entrypoint::MAX_PERMITTED_DATA_INCREASE bytes.

Note: Memory used to grow is already zero-initialized upon program entrypoint and re-zeroing it wastes compute units. If within the same call a program reallocs from larger to smaller and back to larger again the new space could contain stale data. Pass true for zero_init in this case, otherwise compute units will be wasted re-zero-initializing.

Safety

This method makes assumptions about the layout and location of memory referenced by AccountInfo fields. It should only be called for instances of AccountInfo that were created by the runtime and received in the process_instruction entrypoint of a program.

pub fn reassign(&self, new_owner: &Pubkey)
