Reasons the program may fail

Variants

Custom(u32)

Allows on-chain programs to implement program-specific error types and see them returned by the Atlas runtime. A program-specific error may be any type that is represented as or serialized to a u32 integer.

InvalidInstructionData

InvalidAccountData

AccountDataTooSmall

InsufficientFunds

IncorrectProgramId

MissingRequiredSignature

AccountAlreadyInitialized

UninitializedAccount

NotEnoughAccountKeys

AccountBorrowFailed

MaxSeedLengthExceeded

BorshIoError

AccountNotRentExempt

UnsupportedSysvar

IllegalOwner

Implementations

impl ProgramError

pub fn to_str<E>(&self) -> &'static str

where E: 'static + ToStr + TryFrom<u32>,

Get an appropriate error string given a program error and an expected error type, if the error implements TryFrom<u32> and ToStr.

Example

#[derive(num_enum::TryFromPrimitive)]
#[repr(u32)]
enum MyError {
    A,
    B,
}

impl atlas_program_error::ToStr for MyError {
    fn to_str(&self) -> &'static str {
        match self {
            MyError::A => "Message for A",
            MyError::B => "Some other message for B",
        }
    }
}

let program_error = atlas_program_error::ProgramError::Custom(1);
assert_eq!("Some other message for B", program_error.to_str::<MyError>());

Trait Implementations

impl Clone for ProgramError

fn clone(&self) -> ProgramError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProgramError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProgramError

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProgramError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProgramError

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

Formats the value using the given formatter.

impl Error for ProgramError

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<Error> for ProgramError

fn from(_error: Error) -> ProgramError

Converts to this type from the input type.

impl From<AddressError> for ProgramError

fn from(error: AddressError) -> ProgramError

Converts to this type from the input type.

impl From<SystemError> for ProgramError

fn from(e: SystemError) -> ProgramError

Converts to this type from the input type.

impl From<u64> for ProgramError

fn from(error: u64) -> ProgramError

Converts to this type from the input type.

impl PartialEq for ProgramError

fn eq(&self, other: &ProgramError) -> 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.

impl Serialize for ProgramError

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<InstructionError> for ProgramError

type Error = InstructionError

The type returned in the event of a conversion error.

fn try_from( error: InstructionError, ) -> Result<ProgramError, <ProgramError as TryFrom<InstructionError>>::Error>

Performs the conversion.
