Enum RecordKeyError 

pub enum RecordKeyError {
    Empty,
    TooLong(usize),
    InvalidCharacter(char),
    RelativePath(String),
}

Why a string is not a usable record key.

Variants

Empty

Empty, which would make the record unaddressable.

TooLong(usize)

Over MAX_RECORD_KEY_LENGTH characters.

InvalidCharacter(char)

A character outside A-Za-z0-9._:~-.

RelativePath(String)

The key is . or ...

Both are legal under the character rule and both are path traversal waiting to happen, because a record key is the last segment of an at:// URI and of many implementations’ file layouts.

Trait Implementations

impl Clone for RecordKeyError

fn clone(&self) -> RecordKeyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordKeyError

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

Formats the value using the given formatter.

impl Display for RecordKeyError

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

Formats the value using the given formatter.

impl Error for RecordKeyError

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 RecordKeyError

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