Errors returned when a policy value cannot represent a safe request.

Variants

EmptyPath

A path argument was empty.

ExpectedAbsolute

A path that must be absolute was relative.

Fields

path: PathBuf

The path that was supplied by the caller.

ExpectedRelative

A path that must be workspace-relative was absolute.

Fields

path: PathBuf

The path that was supplied by the caller.

PathContainsNul

A path contained a NUL character that an operating-system backend cannot use.

Fields

path: PathBuf

The path that was supplied by the caller.

ParentTraversal

A workspace-relative path attempts to escape its root.

Fields

path: PathBuf

The workspace-relative path that attempted to escape its root.

InvalidDomainPattern

A domain pattern is empty or malformed.

Fields

pattern: String

The domain pattern that failed validation.

ResolvedAddressMismatch

An IP-literal target claimed a resolved address for a different IP.

Fields

literal: String

The normalized literal supplied as the target host.

address: SocketAddr

The inconsistent address in the resolution snapshot.

InvalidGlobPattern

A filesystem glob is empty or malformed.

Fields

pattern: String

The glob pattern that failed validation.

reason: String

The reason the pattern is invalid.

UnsupportedGlobAccess

A glob requested an access mode that is not portable across backends.

Fields

access: AccessMode

The access mode requested for the glob.

InvalidProtectedPath

A protected relative path is empty or unsafe.

Fields

path: PathBuf

The protected path that failed validation.

reason: String

The reason the path is invalid.

InvalidContext

A path resolution context contains an invalid value.

Fields

message: String

A human-readable explanation of the invalid context.

InvalidRule

A policy rule is internally inconsistent.

Fields

message: String

A human-readable explanation of the inconsistent rule.

Trait Implementations

impl Clone for PolicyError

fn clone(&self) -> PolicyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyError

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

Formats the value using the given formatter.

impl Display for PolicyError

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

Formats the value using the given formatter.

impl Eq for PolicyError

impl Error for PolicyError

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 PolicyError

fn eq(&self, other: &PolicyError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
