Struct FfiError 

pub struct FfiError {
    pub code: ErrorCode,
    pub message: String,
}

A flat, FFI-friendly error: a category plus a human-readable message.

Fields

code: ErrorCode

The error’s coarse category.

message: String

A human-readable description of what went wrong.

Implementations

impl FfiError

pub fn new(code: ErrorCode, message: impl Into<String>) -> Self

Creates an error from a category and message.

Trait Implementations

impl Clone for FfiError

fn clone(&self) -> FfiError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FfiError

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

Formats the value using the given formatter.

impl Display for FfiError

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

Formats the value using the given formatter.

impl Eq for FfiError

impl Error for FfiError

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 From<MatchError> for FfiError

fn from(e: MatchError) -> Self

Converts to this type from the input type.

impl From<ModelError> for FfiError

fn from(e: ModelError) -> Self

Converts to this type from the input type.

impl From<ParseError> for FfiError

fn from(e: ParseError) -> Self

Converts to this type from the input type.

impl PartialEq for FfiError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
