Struct SysErr 

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

Raw error code returned across the syscall boundary.

Wraps the i32 produced by a syscall; the known values are the SyscallErrorCode constants, with kSyscallErrorCodeNone (0) meaning success. Unknown codes are preserved as-is, so Debug falls back to the numeric value.

Tuple Fields

0: i32

Implementations

impl SysErr

pub const fn const_write_cxs<const __N: usize>(&self, w: &mut ConstWriter<__N>)

pub const fn const_write_txs<const __N: usize>(&self, w: &mut ConstWriter<__N>)

pub const fn const_cxs_size(&self) -> usize

Returns the CXS encoded size of this value in bytes.

pub const fn const_txs_size(&self) -> usize

Returns the TXS encoded size of this value in bytes.

impl SysErr

pub fn is_code(&self, code: SyscallErrorCode) -> bool

Returns whether this error carries exactly code.

pub fn is_none(&self) -> bool

Returns whether this is the success code (kSyscallErrorCodeNone).

pub fn is_some(&self) -> bool

Returns whether this is any code other than success.

pub fn is_storage_key_not_exist(self) -> bool

Returns whether the syscall failed because the storage key does not exist (kSyscallErrorCodeStorageKeyNotExist).

pub fn is_invalid_input(self) -> bool

Returns whether the syscall rejected its input (kSyscallErrorCodeInvalidSyscallInput).

Trait Implementations

impl Clone for SysErr

fn clone(&self) -> SysErr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstMaxSize for SysErr

const MAX_SIZE: Option<usize>

Worst-case CXS encoded size in bytes, or None if unbounded.

impl ConstMaxSize for SysErr

const MAX_SIZE: Option<usize>

Worst-case TXS encoded size in bytes, or None if unbounded.

impl ContractTypeRefSpec for SysErr

const INFO: ContractTypeInfo<'static>

The type reference. Transitive type definitions are not carried here; they are retained via the linker-anchor mechanism (__THRUPUT_SPEC_ANCHOR_ROOT) and resolved by spec-tool.

const SIGNED_PREIMAGE: Option<&'static ContractTypeView<'static>> = _

How this type appears as a signed-token preimage (ContractTypeView::SignedToken’s payload): the type itself by default, or None for a type-erased payload (the SDK’s Opaque overrides this).

impl Copy for SysErr

impl Debug for SysErr

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

Formats the value using the given formatter.

impl Display for SysErr

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

Formats the value using the given formatter.

impl EncodesAs<SysErr> for SysErr

impl Eq for SysErr

impl Error for SysErr

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<SyscallErrorCode> for SysErr

fn from(code: SyscallErrorCode) -> SysErr

Converts to this type from the input type.

impl PartialEq for SysErr

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

Equality operator ==.

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

Inequality operator !=.

impl<'_r> ReadXDR<'_r> for SysErr

fn read_xdr<R>(r: &mut R) -> Result<SysErr, ReadError>

where R: Reader<'_r>,

Reads an XDR value from the reader.

fn read_xdr_in_place<R, '__xdrs_s>( r: &mut R, __xdrs_slot: Slot<'__xdrs_s, SysErr>, ) -> Result<Init<'__xdrs_s, SysErr>, ReadError>

where R: Reader<'_r>,

Reads an XDR value directly into slot, without first building it on the stack.

impl StructuralPartialEq for SysErr

impl WriteXDR for SysErr

fn write_xdr<F, W>(&self, w: &mut W) -> Result<(), WriteError>

where W: Writer<F>,

Writes this value as XDR data to the writer.

unsafe fn write_xdr_unchecked<F, W>(&self, w: &mut W)

where W: WriterUnchecked<F>,

Writes this value as XDR data to the writer, without runtime checks.
