Enum GrantError 

#[non_exhaustive]
pub enum GrantError {
    Unknown {
        name: String,
        supported: String,
    },
    Quota {
        name: String,
    },
    Internal {
        name: String,
    },
}

Failure to interpret a capability grant string.

Returned by Capability::parse_grant; the host-facing parsers map each variant onto their own reporting policy (hard error, skip, or warn).

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.

Unknown

The name matches no known capability.

Fields

name: String

The rejected input string.

supported: String

The /-joined list of grantable names, for the message.

Quota

The capability is a resource quota needing a numeric value.

Fields

name: String

The canonical capability name.

Internal

The capability is internal / first-party and not grantable to guests.

Fields

name: String

The canonical capability name.

Trait Implementations

impl Eq for GrantError

impl Error for GrantError

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 GrantError

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

Equality operator ==.

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

Inequality operator !=.
