Enum Error 

#[non_exhaustive]
pub enum Error {
    GrantDenied {
        grant: String,
    },
    RateLimited,
    Unavailable(String),
    Invalid(String),
    Json(String),
    NotAttached {
        surface: String,
    },
    WrongModel {
        surface: String,
        expected: Model,
        found: Model,
    },
}

Why a host call or a surface operation did not run.

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.

GrantDenied

The manifest does not carry the grant the call needs. grant names it (values.read:git.main, account.read, …): add it to standard-plugin.json with a reason.

Fields

grant: String

RateLimited

The per-plugin rate limit for this call kind was reached.

Unavailable(String)

The backing service is not reachable right now.

Invalid(String)

The host rejected the arguments (an unknown surface id, an oversized value, a key outside the plugin’s namespace).

Json(String)

A payload did not serialize or deserialize.

NotAttached

The surface has no buffer yet: the viewer has not laid it out.

Fields

surface: String

WrongModel

The manifest declares the surface in the other model.

Fields

surface: String

expected: Model

found: Model

Implementations

impl Error

pub fn denied_grant(&self) -> Option<&str>

The missing grant, for a Error::GrantDenied.

Trait Implementations

impl Clone for Error

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 Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.
