Enum StreamReadError 

#[non_exhaustive]
pub enum StreamReadError {
    Source(Error),
}

Real error from Stream::try_read — the underlying source surfaced an I/O failure.

Status conditions (seek pending, data not ready, variant change, retry) are not errors and are carried in StreamReadOutcome::Pending with a typed PendingReason. Only genuine source failures end up here.

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.

Source(Error)

Anything surfaced by the underlying Source as a real error.

Trait Implementations

impl Debug for StreamReadError

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

Formats the value using the given formatter.

impl Display for StreamReadError

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

Formats the value using the given formatter.

impl Error for StreamReadError

fn source(&self) -> Option<&(dyn StdError + '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.
