Struct ProviderError 

pub struct ProviderError {
    pub message: String,
    pub retryable: bool,
}

Error surfaced by a provider adapter.

Fields

message: String

retryable: bool

Implementations

impl ProviderError

pub const CANCELLED_MESSAGE: &str = "failed to execute provider request: request cancelled"

Sentinel message produced by ProviderError::cancelled and recognized by is_cancelled. New consumers should prefer the constructor / predicate over inline message comparison.

pub fn new(message: impl Into<String>, retryable: bool) -> Self

Build a provider error with an explicit retryability flag.

pub fn cancelled() -> Self

Construct a non-retryable cancellation error with the canonical message. Existing consumers that match on message text continue to work; new consumers should use is_cancelled() to distinguish.

pub fn is_cancelled(&self) -> bool

Whether this error is the canonical cancellation sentinel.

Trait Implementations

impl Clone for ProviderError

fn clone(&self) -> ProviderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProviderError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProviderError

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

Formats the value using the given formatter.

impl Eq for ProviderError

impl Error for ProviderError

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 JsonSchema for ProviderError

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for ProviderError

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

impl Serialize for ProviderError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
