Enum NameError 

#[non_exhaustive]
pub enum NameError {
    Empty,
    TooLong(usize),
    NonAscii,
    InvalidChar(u8),
}

Error when creating a NameStr from a string.

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.

Empty

The name string is empty (must be at least 1 character).

TooLong(usize)

The name string exceeds the maximum length of 4 characters. Contains the actual length provided.

NonAscii

The name contains non-ASCII characters.

InvalidChar(u8)

The name contains a character not in the allowed set (0-4, a-z). Contains the invalid byte value.

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 Debug for NameError

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

Formats the value using the given formatter.

impl Display for NameError

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

Formats the value using the given formatter.

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 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.
