Enum NameError 

#[non_exhaustive]
pub enum NameError {
    LabelTooLong(LabelTooLongDetail),
    NameTooLong(NameTooLongDetail),
    EmptyLabel,
}

Reasons a string cannot be accepted as a Name.

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.

LabelTooLong(LabelTooLongDetail)

A single label exceeded MAX_LABEL_BYTES.

NameTooLong(NameTooLongDetail)

The complete name exceeded MAX_NAME_BYTES.

EmptyLabel

The input contained an empty label (e.g. consecutive dots).

Implementations

impl NameError

pub const fn is_label_too_long(&self) -> bool

Returns true if this value is of type LabelTooLong. Returns false otherwise

pub const fn is_name_too_long(&self) -> bool

Returns true if this value is of type NameTooLong. Returns false otherwise

pub const fn is_empty_label(&self) -> bool

Returns true if this value is of type EmptyLabel. Returns false otherwise

impl NameError

pub fn unwrap_label_too_long(self) -> LabelTooLongDetail

Unwraps this value to the NameError::LabelTooLong variant. Panics if this value is of any other type.

pub fn unwrap_label_too_long_ref(&self) -> &LabelTooLongDetail

Unwraps this reference to the NameError::LabelTooLong variant. Panics if this value is of any other type.

pub fn unwrap_name_too_long(self) -> NameTooLongDetail

Unwraps this value to the NameError::NameTooLong variant. Panics if this value is of any other type.

pub fn unwrap_name_too_long_ref(&self) -> &NameTooLongDetail

Unwraps this reference to the NameError::NameTooLong variant. Panics if this value is of any other type.

pub fn unwrap_empty_label(self)

Unwraps this value to the NameError::EmptyLabel variant. Panics if this value is of any other type.

pub fn unwrap_empty_label_ref(&self)

Unwraps this reference to the NameError::EmptyLabel variant. Panics if this value is of any other type.

impl NameError

pub fn try_unwrap_label_too_long( self, ) -> Result<LabelTooLongDetail, TryUnwrapError<Self>>

Attempts to unwrap this value to the NameError::LabelTooLong variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_label_too_long_ref( &self, ) -> Result<&LabelTooLongDetail, TryUnwrapError<&Self>>

Attempts to unwrap this reference to the NameError::LabelTooLong variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_name_too_long( self, ) -> Result<NameTooLongDetail, TryUnwrapError<Self>>

Attempts to unwrap this value to the NameError::NameTooLong variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_name_too_long_ref( &self, ) -> Result<&NameTooLongDetail, TryUnwrapError<&Self>>

Attempts to unwrap this reference to the NameError::NameTooLong variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_empty_label(self) -> Result<(), TryUnwrapError<Self>>

Attempts to unwrap this value to the NameError::EmptyLabel variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_empty_label_ref(&self) -> Result<(), TryUnwrapError<&Self>>

Attempts to unwrap this reference to the NameError::EmptyLabel variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

Trait Implementations

impl Clone for NameError

fn clone(&self) -> NameError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NameError

impl Debug for NameError

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

Formats the value using the given formatter.

impl Display for NameError

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

Formats the value using the given formatter.

impl Eq for NameError

impl Error for NameError

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 NameError

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 PartialEq for NameError

fn eq(&self, other: &NameError) -> 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.
