Enum ErrorCode 

#[non_exhaustive]
pub enum ErrorCode {
    InvalidOperator,
    InvalidArguments,
    VariableNotFound,
    InvalidContextLevel,
    TypeError,
    ArithmeticError,
    Custom,
    ParseError,
    Thrown,
    FormatError,
    IndexOutOfBounds,
    ConfigurationError,
    BudgetExceeded,
}

What kind of error an Error is, without the details: one variant per ErrorKind variant, Copy, comparable and hashable. Read it with Error::code.

Every variant exists in every build, whatever features are enabled, and Self::as_str spells it the way Error::tag always has, so a host can switch on the code instead of comparing tag strings, and the bindings carry the same names on the wire.

#[non_exhaustive]: a later release may add kinds, so a match needs a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidOperator

ErrorKind::InvalidOperator.

InvalidArguments

ErrorKind::InvalidArguments.

VariableNotFound

ErrorKind::VariableNotFound.

InvalidContextLevel

ErrorKind::InvalidContextLevel.

TypeError

ErrorKind::TypeError.

ArithmeticError

ErrorKind::ArithmeticError.

Custom

ErrorKind::Custom.

ParseError

ErrorKind::ParseError.

Thrown

ErrorKind::Thrown.

FormatError

ErrorKind::FormatError.

IndexOutOfBounds

ErrorKind::IndexOutOfBounds.

ConfigurationError

ErrorKind::ConfigurationError.

BudgetExceeded

ErrorKind::BudgetExceeded.

Implementations

impl ErrorCode

pub const ALL: &'static [ErrorCode]

Every code, in declaration order.

pub const fn as_str(self) -> &'static str

The code’s name, which is also the variant’s name and Error::tag. Stable across releases.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl FromStr for ErrorCode

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse a code from its exact (case-sensitive) name.

type Err = UnknownErrorCode

The associated error which can be returned from parsing.

impl Hash for ErrorCode

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 ErrorCode

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ErrorCode

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ErrorCode

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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