Enum CloudError 

#[non_exhaustive]
pub enum CloudError {
    Credential {
        message: String,
        source: Option<Box<dyn Error + Send + Sync + 'static>>,
    },
    Signing {
        message: String,
        source: Option<Box<dyn Error + Send + Sync + 'static>>,
    },
    Network {
        message: String,
        source: Option<Box<dyn Error + Send + Sync + 'static>>,
    },
    Config(String),
    EventStream(EventStreamParseError),
}

Failures emitted by cloud-layer machinery (credential resolution, signing, refreshable token plumbing, binary frame parsing).

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.

Credential

Credential resolver returned an error or no credentials.

Fields

message: String

Human-readable summary.

source: Option<Box<dyn Error + Send + Sync + 'static>>

Underlying credential-provider error.

Signing

SigV4 / AAD signing failed.

Fields

message: String

Human-readable summary.

source: Option<Box<dyn Error + Send + Sync + 'static>>

Underlying signer error.

Network

Network / HTTP failure.

Fields

message: String

Human-readable summary.

source: Option<Box<dyn Error + Send + Sync + 'static>>

Underlying transport error.

Config(String)

Configuration error — missing region, malformed URL, etc.

EventStream(EventStreamParseError)

Available on crate feature aws only.

Event-stream frame parser failure (Bedrock binary protocol).

Implementations

impl CloudError

pub fn credential<E>(source: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a credential-provider failure preserving the source chain.

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

Construct a CloudError::Credential from a bare message.

pub fn signing<E>(source: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a signer failure preserving the source chain.

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

Construct a CloudError::Signing from a bare message.

pub fn network<E>(source: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a transport failure preserving the source chain.

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

Construct a CloudError::Network from a bare message.

Trait Implementations

impl Debug for CloudError

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

Formats the value using the given formatter.

impl Display for CloudError

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

Formats the value using the given formatter.

impl Error for CloudError

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<CloudError> for Error

fn from(err: CloudError) -> Self

Converts to this type from the input type.

impl From<EventStreamParseError> for CloudError

fn from(source: EventStreamParseError) -> Self

Converts to this type from the input type.
