Enum Error 

pub enum Error {
    AbiMismatch {
        expected: u32,
        found: u32,
    },
    OutOfMemory,
    Nul,
    Library(String),
    Json(String),
}

Why a call failed.

Variants

AbiMismatch

The library implements another version of the interface.

Fields

expected: u32

The version this crate was written against.

found: u32

The version the library reports.

OutOfMemory

The library could not allocate a handle.

Nul

A string argument held a NUL byte, which C cannot take.

Library(String)

The library’s own message: a log that cannot be read, a preference file refused, a transform that failed to remake its outputs.

Json(String)

The library returned JSON this crate could not parse: a version skew the ABI version did not catch.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &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.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
