Struct soroban_wasmi::Error

pub struct Error { /* private fields */ }

The generic Wasmi root error type.

Implementations

impl Error

pub fn new<T>(message: T) -> Self

where T: Into<String>,

Creates a new Error described by a message.

pub fn host<E>(host_error: E) -> Self

where E: HostError,

Creates a custom HostError.

pub fn i32_exit(status: i32) -> Self

Creates a new Error representing an explicit program exit with a classic i32 exit status value.

Note

This is usually used as return code by WASI applications.

pub fn kind(&self) -> &ErrorKind

Returns the ErrorKind of the Error.

pub fn as_trap_code(&self) -> Option<TrapCode>

Returns a reference to TrapCode if Error is a TrapCode.

pub fn i32_exit_status(&self) -> Option<i32>

Returns the classic i32 exit program code of a Trap if any.

Otherwise returns None.

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: HostError,

Downcasts the Error into the T: HostError if possible.

Returns None otherwise.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T>

where T: HostError,

Downcasts the Error into the T: HostError if possible.

Returns None otherwise.

pub fn downcast<T>(self) -> Option<T>

where T: HostError,

Consumes self to downcast the Error into the T: HostError if possible.

Returns None otherwise.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
