Variants

InsufficientFunds

Insufficient funds for the operation requested.

MintMismatch

Account not associated with this Mint.

OwnerMismatch

Owner does not match.

FixedSupply

This token's supply is fixed and new tokens cannot be minted.

AlreadyInUse

The account cannot be initialized because it is already being used.

OwnerRequiredIfNoInitialSupply

An owner is required if initial supply is zero.

InvalidNumberOfProvidedSigners

Invalid number of provided signers.

InvalidNumberOfRequiredSigners

Invalid number of required signers.

UninitializedState

State is uninitialized.

NativeNotSupported

Instruction does not support native tokens

NonNativeNotSupported

Instruction does not support non-native tokens

InvalidInstruction

Invalid instruction

Trait Implementations

impl Clone for TokenError

fn clone(&self) -> TokenError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenError

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

Formats the value using the given formatter.

impl<T> DecodeError<T> for TokenError

fn type_of() -> &'static str

fn decode_custom_error_to_enum(custom: u32) -> Option<E> where
    E: FromPrimitive, 

impl Display for TokenError

fn fmt(&self, __formatter: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for TokenError

impl Error for TokenError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
