A failure parsing one scope atom or a whole scope string.

Variants

TooLong

The scope string is longer than the bound it was read under: MAX_SCOPE_BYTES for a request, MAX_GRANT_BYTES for a grant.

Fields

len: usize

How long the string is.

max: usize

The bound it was read under.

TooManyAtoms

The scope string names more scopes than the bound it was read under: MAX_SCOPE_ATOMS for a request, MAX_GRANT_ATOMS for a grant.

Fields

count: usize

How many scopes the string names.

max: usize

The bound it was read under.

AtomTooLong(usize)

An atom is longer than MAX_ATOM_BYTES.

ForbiddenCharacter(char)

An atom holds a character outside RFC 6749’s scope-token: printable ASCII except " and \.

Empty

The atom was the empty string.

UnknownKind(String)

The kind: prefix is not one this grammar defines.

MalformedNsid(String)

The collection or method value is not a valid NSID or NSID wildcard.

MalformedMime(String)

The MIME value is not type/subtype, with either half a *.

UnknownAction(String)

An action= value the atom’s kind does not define.

UnknownAttribute(String)

An attr value the atom’s kind does not define.

SeveralScopes(String)

Scope::parse was given an atom that names several scopes, one for each collection or method it lists.

UnknownTransition(String)

A transition: atom named something other than the three defined legacy scopes.

MissingValue(String)

The atom gave no value for the parameter its kind requires, such as repo:’s collection. An include: whose value names no permission set still parses; see Include::new.

MalformedQuery(String, String)

A ?query segment had a pair with no =.

Trait Implementations

impl Clone for ScopeParseError

fn clone(&self) -> ScopeParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScopeParseError

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

Formats the value using the given formatter.

impl Display for ScopeParseError

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

Formats the value using the given formatter.

impl Error for ScopeParseError

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 ScopeParseError

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