Enum VAError 

pub enum VAError {
    MissingSigner {
        field: &'static str,
    },
    NotWritable {
        field: &'static str,
    },

    WrongDiscriminator {
        field: &'static str,

}

Why account validation failed. field is the struct field name that failed.

Trait Implementations

impl Clone for VAError

fn clone(&self) -> VAError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VAError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VAError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VAError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<VAError> for ProgramError

So a handler returning ProgramResult can use Transfer::try_accounts(...)? directly. Each variant maps to a distinct custom code so clients can disambiguate the failed check.

fn from(e: VAError) -> Self

Converts to this type from the input type.

impl PartialEq for VAError

fn eq(&self, other: &VAError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
