Struct SyscallErrorCode 

#[repr(transparent)]
pub struct SyscallErrorCode(pub i32);

Error codes returned by system calls. Each syscall can return a specific subset of these error codes. Check the syscalls.yaml documentation for which errors each syscall can return.

Implementations

impl SyscallErrorCode

pub const kSyscallErrorCodeNone: Self

No error

pub const kSyscallErrorCodeFault: Self

Out of bounds pointer to contract memory passed to syscall

pub const kSyscallErrorCodeNoSyscall: Self

System call for supplied number is not supported

pub const kSyscallErrorCodeIsRootTransaction: Self

Cannot call get_msg_sender on root invocation

pub const kSyscallErrorCodeReentrance: Self

Reentrance guard violation

pub const kSyscallErrorCodeContractAlreadyDeployed: Self

Attempt made to deploy a contract twice (same nonce and contract hash, from same address)

pub const kSyscallErrorCodeNoReturnBufferAvailable: Self

No return buffer is available. Either the most recent subcall faulted, or there have been no subcalls within this call frame.

pub const kSyscallErrorCodeInvalidSyscallInput: Self

Invalid input to a syscall, such as subtracting below 0 on an nnint or a bytestring that is too long

pub const kSyscallErrorCodeStorageKeyNotExist: Self

Accessing a storage key that does not exist in the current view

pub const kSyscallErrorCodeNoRetrocausalQueueEntry: Self

No entry in the retrocausal queue to consume

pub const kSyscallErrorCodeRetrocausalQueueReadLimitReached: Self

The transaction has reached its per-transaction limit on concurrent retrocausal-queue reads (kMaxConcurrentRcqReadsPerTx). This is a resource limit, not a malformed call, and does not by itself fail the transaction; a contract may use it as a stop condition (e.g. drain a queue until it returns this).

pub const kSyscallErrorCodeInvokeDepthExceeded: Self

The invocation would exceed the network’s cross-invoke depth bound (kConfigParamMaxCrossInvokeDepth), which limits how many invocation frames one transaction may hold open at once. Like the retrocausal-queue read limit this is a resource limit, not a malformed call: the same invocation succeeds from a shallower frame. It is reported before any child frame runs, so the syscall is a complete no-op and the caller’s invoke outputs are left untouched.
