pub fn is_writable(&self) -> bool

Returns whether this account is writable (instruction wide)

pub fn is_owned_by_current_program(&self) -> bool

Returns true if the owner of this account is the current InstructionContexts last program (instruction wide)

pub fn can_data_be_changed(&self) -> Result<(), InstructionError>

Returns an error if the account data can not be mutated by the current program

pub fn can_data_be_resized(
    &self,
    new_length: usize
