Enum Error 

pub enum Error {
    Rnp {
        code: u32,
        kind: ErrorKind,
        message: String,
    },
    NullPointer,
    NulByte,
    PathNul,
    UnknownVariant {
        kind: &'static str,
        value: String,
    },
    Io {
        source: Error,
    },
}

A failure returned by the underlying librnp call, or a wrapper-level precondition violation.

Variants

Rnp

The RNP call returned a non-success result code.

Fields

code: u32

kind: ErrorKind

message: String

NullPointer

A required pointer/handle was unexpectedly null.

NulByte

A NUL byte was found in a string that must be passed to librnp as a C string.

PathNul

A NUL byte was found in a path that must be passed to librnp.

UnknownVariant

A string-to-enum conversion failed because the string doesn’t match any known variant. Surfaces from FromStr impls on the model enums.

Fields

kind: &'static str

value: String

Io

An I/O operation at the Rust/C boundary failed.

Fields

source: Error

Implementations

impl Error

pub fn kind(&self) -> ErrorKind

Coarse category of the failure, regardless of the underlying cause.

pub fn rnp_code(&self) -> Option<u32>

The raw rnp_result_t code if this is an Error::Rnp, else None.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

where Self: Debug + Display,

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.

impl ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<Error> for Error

Bridge std::io::Error into Error so ? works at IO/FFI boundaries.

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Bridge Error into std::io::Error so ? works when a caller is exposing an IO API on top of rnp-rs. The io::Error’s kind is derived from Error::kind where there’s a sensible mapping.

fn from(err: Error) -> Self

Converts to this type from the input type.
