Enum TrustError 

pub enum TrustError {
    Widens {
        dimension: Dimension,
        parent: Level,
        requested: Level,
    },
    EffectNotPermitted {
        effect: String,
        dimension: Dimension,
        required: Level,
        granted: Level,
    },
    NetHostNotAllowed {
        host: String,
        allowed: usize,
    },
    NetUnscoped,
}

Why a requested grant was refused. The runtime contract is refuse, don’t downgrade (design doc §7.5): when a child manifest asks for more than its parent allows we return this error rather than silently clamping.

Trait Implementations

impl Clone for TrustError

fn clone(&self) -> TrustError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrustError

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

Formats the value using the given formatter.

impl Display for TrustError

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

Formats the value using the given formatter.

impl Eq for TrustError

impl Error for TrustError

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 TrustError

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