Struct ErrorStack 

pub struct ErrorStack(/* private fields */);

A snapshot of all records that were on the thread-local OpenSSL error queue.

Returned as the Err variant of every Result<T, ErrorStack> in this crate. The queue is cleared when this is constructed.

Implementations

impl ErrorStack

pub fn drain() -> Self

Drain the current thread’s OpenSSL error queue into a new ErrorStack.

After this call the queue is empty. This is the canonical way to turn an OpenSSL failure into a Rust error value.

pub fn is_empty(&self) -> bool

Returns true if the stack contains no errors.

pub fn len(&self) -> usize

Number of error records.

pub fn errors(&self) -> impl Iterator<Item = &Error>

Iterate over the individual error records (oldest first).

Trait Implementations

impl Clone for ErrorStack

fn clone(&self) -> ErrorStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorStack

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

Formats the value using the given formatter.

impl Display for ErrorStack

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

Formats the value using the given formatter.

impl Error for ErrorStack

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.
