Enum StreamError 

pub enum StreamError {
    Response(String),
}

Why a body writer is fallible.

The only reachable variant is the response assembly. A body whose frames are already encoded cannot fail mid-stream, and the Stream item type is a Result only because Body::from_stream requires one — an unencodable payload is turned into a refusal by decide long before it could reach the writer.

Variants

Response(String)

The response could not be assembled.

Every header this module sets is a compile-time literal, so nothing in the crate can actually trigger this today. It is handled rather than unwrapped because the alternative is a panic on a request path, and a request path is the worst place to put one.

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

impl Eq for StreamError

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.

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for StreamError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
