Enum IdentifierError 

pub enum IdentifierError {
    NotCanonicalized {
        name: RawIdentifier,
    },
    Reserved {
        name: RawIdentifier,
    },
    InvalidStart {
        name: RawIdentifier,
        invalid_start: char,
    },
    InvalidContinue {
        name: RawIdentifier,
        invalid_continue: char,
    },
    Empty {},
}

A reason that a string the user used is not allowed.

Variants

NotCanonicalized

The identifier is not in Unicode Normalization Form C.

TODO(1.0): We should canonicalize identifiers, rather than simply rejecting non-canonicalized identifiers. However, this will require careful testing of codegen in both modules and clients, to ensure that the canonicalization is done consistently. Otherwise, strange name errors will result.

Trait Implementations

impl Debug for IdentifierError

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

Formats the value using the given formatter.

impl Display for IdentifierError

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

Formats the value using the given formatter.

impl Error for IdentifierError

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 Ord for IdentifierError

fn cmp(&self, other: &IdentifierError) -> 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 IdentifierError

fn eq(&self, other: &IdentifierError) -> 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 IdentifierError

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