Struct Error 

pub struct Error { /* private fields */ }

A detailed error reported as part of an ErrorStack.

Implementations

impl Error

pub fn get() -> Option<Error>

Pops the first error off the OpenSSL error stack.

This corresponds to ERR_get_error_line_data.

pub fn put(&self)

Pushes the error back onto the OpenSSL error stack.

This corresponds to ERR_put_error.

pub fn library_reason(&self, library_code: ErrLib) -> Option<c_int>

Get {lib}_R_{reason} reason code for the given library, or None if the error is from a different library.

Libraries are identified by [ERR_LIB_{name}(ffi::ERR_LIB_SSL) constants.

pub fn code(&self) -> c_uint

👎Deprecated: use library_reason() to compare error codes

Returns a raw OpenSSL packed error code for this error, which can’t be reliably compared to any error constant.

Use Error::library_code() and Error::library_reason() instead. Packed error codes are different than SSL error codes.

pub fn library(&self) -> Option<&'static str>

Returns the name of the library reporting the error, if available.

pub fn library_code(&self) -> c_int

Returns the raw OpenSSL error constant for the library reporting the error (ERR_LIB_{name}).

Error reason codes are not globally unique, but scoped to each library.

pub fn function(&self) -> Option<&'static str>

Returns None. Boring doesn’t use function codes.

pub fn reason(&self) -> Option<&str>

Returns the reason for the error.

pub fn reason_code(&self) -> c_int

Returns library-specific reason code corresponding to some of the {lib}_R_{reason} constants.

Reason codes are ambiguous, and different libraries reuse the same numeric values for different errors. Use Error::library_reason to compare error codes.

For ERR_LIB_SYS the reason code is errno. ERR_LIB_USER can use any values. Other libraries may use ERR_R_* or their own codes.

pub fn file(&self) -> &'static str

Returns the name of the source file which encountered the error.

pub fn line(&self) -> u32

Returns the line in the source file which encountered the error.

0 if unknown

pub fn data(&self) -> Option<&str>

Returns additional data describing the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
