Struct spacetimedb_vm::errors::ErrorLang

pub struct ErrorLang {
    pub kind: ErrorKind,
    pub msg: Option<String>,
    pub context: Option<Vec<ErrorCtx>>,
}

Define the main User Error type for the VM

Fields

kind: ErrorKind

msg: Option<String>

context: Option<Vec<ErrorCtx>>

Optional context for the Error: Which record was not found, what value was invalid, etc.

Implementations

impl ErrorLang

pub fn new(kind: ErrorKind, msg: Option<&str>) -> Self

pub fn with_ctx(self, of: ErrorCtx) -> Self

Trait Implementations

impl Clone for ErrorLang

fn clone(&self) -> ErrorLang

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorLang

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

Formats the value using the given formatter.

impl Display for ErrorLang

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

Formats the value using the given formatter.

impl Error for ErrorLang

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

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<ErrorLang> for ErrorVm

fn from(source: ErrorLang) -> Self

Converts to this type from the input type.

impl From<ErrorType> for ErrorLang

fn from(x: ErrorType) -> Self

Converts to this type from the input type.

impl From<ErrorVm> for ErrorLang

fn from(err: ErrorVm) -> Self

Converts to this type from the input type.

impl From<RelationError> for ErrorLang

fn from(err: RelationError) -> Self

Converts to this type from the input type.

impl Hash for ErrorLang

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ErrorLang

fn cmp(&self, other: &ErrorLang) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ErrorLang

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ErrorLang

fn partial_cmp(&self, other: &ErrorLang) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
