Enum HostExtensionError 

pub enum HostExtensionError {
    InvalidInput(String),
    MissingCapability(String),
    PermissionDenied(String),
    NotFound(String),
    SchemaInvalid(String),
    Internal(String),
}

Host-side mirror of WIT greentic:extension-base/types@0.1.0::extension-error.

Host-level failure that a role compiler may surface. Mirrored here so RoleError::Host can carry the variant without dragging in the bindgen-generated type at the public API boundary.

The code() method returns a stable kebab-case string that matches the WIT extension-error variant name — used as the wire contract for the designer’s {ok, data, error} response envelope. Never rename existing codes without a wire-breaking version bump.

Implementations

impl HostExtensionError

pub fn code(&self) -> &'static str

Stable kebab-case code matching the WIT extension-error variant name. This string is the wire contract for the designer’s {ok, data, error} envelope — never rename existing codes.

Trait Implementations

impl Clone for HostExtensionError

fn clone(&self) -> HostExtensionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostExtensionError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HostExtensionError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HostExtensionError

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

Formats the value using the given formatter.

impl Error for HostExtensionError

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<HostExtensionError> for RoleError

fn from(source: HostExtensionError) -> Self

Converts to this type from the input type.

impl Serialize for HostExtensionError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
