Enum CompileError

pub enum CompileError {
    ShadowedLabel(String),
    UndeclaredLabel(String),
    ContinueOutsideLoop,
    BreakOutsideLoop,
    FollowingCodeUnreachable,
    UnreachableStatement,
    UnproductiveLoop,
    UnproductiveContinue,
}

A compilation error due to invalid (but parseable) input in the surface macro syntax.

Variants

ShadowedLabel(String)

Error resulting from 'a loop { ... 'a loop { ... }}.

UndeclaredLabel(String)

Error resulting from continue 'a or break 'a which are inside a loop, but not inside any loop with the label 'a.

ContinueOutsideLoop

Error resulting from any call to continue outside of a loop.

BreakOutsideLoop

Error resulting from any call to break outside of a loop.

FollowingCodeUnreachable

Error resulting from control flow analysis finding that a statement unconditionally jumps away from following code.

UnreachableStatement

Error resulting from control flow analysis finding that a statement can never be reached because of preceding control flow.

UnproductiveLoop

Error resulting from unproductive loop analysis finding that a loop is unproductive and cannot be compiled without resulting in typechecker overflow.

UnproductiveContinue

Error resulting from any continue or break which produce an unproductive loop.

Trait Implementations

impl Clone for CompileError

fn clone(&self) -> CompileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompileError

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

Formats the value using the given formatter.

impl Display for CompileError

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

Formats the value using the given formatter.

impl Error for CompileError

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 Hash for CompileError

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 CompileError

fn cmp(&self, other: &CompileError) -> 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.

impl PartialEq for CompileError

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for CompileError

fn partial_cmp(&self, other: &CompileError) -> 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.
