Why an overlay, a parent policy or their merge was refused.

Variants

Io

A file could not be read.

Fields

path: String

reason: String

TooLarge

A file is over MAX_FILE_BYTES.

Fields

path: String

bytes: u64

Overlay(OverlayError)

The overlay broke the tighten-only rule (package A’s error).

Parent(ParentPolicyError)

The parent policy is not acceptable.

IdCollision

Two rules the merge would emit share an id.

Fields

key: String

id: String

NotAChild

profile = "project" but the kernel is not a child kernel.

Cert(String)

The project certificate is missing or does not verify.

ApprovalOverlapsDeny

An overlay approval glob overlaps a glob the parent denies; an approval must never turn a deny into a question.

Fields

key: String

glob: String

parent_glob: String

OverlayMissing

overlay.toml is gone although a non-empty overlay is in force. Clear an overlay with an empty file, never by deleting it.

PinCorrupt

The rollback pin exists but cannot be read.

Fields

path: String

reason: String

PinMissing

No rollback pin, yet the chain records an applied overlay.

Revoked(String)

The project was revoked by its user daemon.

Implementations

impl OverlayError

pub fn key(&self) -> String

The offending key (what weaver doctor prints and BootRefused names).

pub fn boot_message(&self) -> String

The message BootRefused carries.

Trait Implementations

impl Clone for OverlayError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverlayError

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

Formats the value using the given formatter.

impl Display for OverlayError

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

Formats the value using the given formatter.

impl Error for OverlayError

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 From<OverlayError> for OverlayError

fn from(source: OverlayError) -> Self

Converts to this type from the input type.

impl From<ParentPolicyError> for OverlayError

fn from(source: ParentPolicyError) -> Self

Converts to this type from the input type.

impl PartialEq for OverlayError

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

Equality operator ==.

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

Inequality operator !=.
