Enum StreamError 

pub enum StreamError {
    TooLarge,
    Transport(String),
}

Why a RequestStream ended early.

Variants

TooLarge

The body crossed the route’s StreamRoute::max_bytes. The chunk that would have crossed it is refused, not delivered, and the stream is fused from here on.

Transport(String)

The underlying transport failed mid-stream. The text is for logs and never reaches a response body.

Trait Implementations

impl Clone for StreamError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamError

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

Formats the value using the given formatter.

impl Display for StreamError

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

Formats the value using the given formatter.

impl Error for StreamError

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<StreamError> for BlobError

fn from(error: StreamError) -> Self

Converts to this type from the input type.

impl From<StreamError> for Problem

A mid-stream failure is a Problem: a ceiling breach is exactly the 413 request-too-large a buffered route answers with, and a transport failure is a server-side fault the caller cannot fix, so it becomes the generic 500 internal (the same mapping crate::ports::DbError gets — no internals in the body, the error only logged).

fn from(error: StreamError) -> Self

Converts to this type from the input type.
