Implementations

impl Error

pub fn config(message: impl Into<String>) -> Self

Create a configuration error.

pub fn session(message: impl Into<String>) -> Self

Create a session error.

pub fn provider(provider: impl Into<String>, message: impl Into<String>) -> Self

Create a provider error.

pub fn auth(message: impl Into<String>) -> Self

Create an authentication error.

pub fn tool(tool: impl Into<String>, message: impl Into<String>) -> Self

Create a tool error.

pub fn validation(message: impl Into<String>) -> Self

Create a validation error.

pub fn extension(message: impl Into<String>) -> Self

Create an extension error.

pub fn api(message: impl Into<String>) -> Self

Create an API error.

pub const fn hostcall_error_code(&self) -> &'static str

Map this error to a hostcall taxonomy code.

The hostcall ABI requires every error to be one of: timeout, denied, io, invalid_request, or internal.

pub const fn category_code(&self) -> &'static str

Stable machine-readable error category for automation and diagnostics.

pub fn auth_diagnostic(&self) -> Option<AuthDiagnostic>

Classify auth/config errors into stable machine-readable diagnostics.

pub fn hints(&self) -> ErrorHints

Map internal errors to a stable, user-facing hint taxonomy.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
