Struct gcrypt::Error

pub struct Error { /* fields omitted */ }

A type wrapping errors produced by GPG libraries.

Methods

impl Error

fn new(err: u32) -> Error

Creates a new error from a raw error value.

fn raw(&self) -> u32

Returns the raw error value that this error wraps.

fn from_source(source: u32, code: u32) -> Error

Creates a new error from an error source and an error code.

fn from_code(code: u32) -> Error

Creates a new error from an error code using the default error source GPG_ERR_SOURCE_USER_1.

fn last_os_error() -> Error

Returns an error representing the last OS error that occurred.

fn from_errno(code: i32) -> Error

Creates a new error from an OS error code.

fn to_errno(&self) -> i32

Returns the OS error that this error represents.

fn code(&self) -> u32

Returns the error code.

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

Returns a description of the source of the error as a UTF-8 string.

fn raw_source(&self) -> Option<&'static [u8]>

Returns a description of the source of the error as a slice of bytes.

fn description(&self) -> Cow<'static, str>

Returns a printable description of the error.

fn raw_description(&self) -> Cow<'static, [u8]>

Returns a description of the error as a slice of bytes.
