Struct Error 

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

An error returned by a3s-vec.

Fields

code: ErrorCode

Stable machine-readable category.

message: String

Human-readable context. Messages never contain a secret by design.

Implementations

impl Error

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

Creates an error with a stable code and context.

pub fn not_found(message: impl Into<String>) -> Self

pub fn invalid_argument(message: impl Into<String>) -> Self

pub fn permission_denied(message: impl Into<String>) -> Self

pub fn failed_precondition(message: impl Into<String>) -> Self

pub fn internal(message: impl Into<String>) -> Self

pub fn resource_exhausted(message: impl Into<String>) -> Self

pub fn not_supported(message: impl Into<String>) -> Self

pub fn is_not_found(&self) -> bool

pub fn is_already_exists(&self) -> bool

pub fn is_invalid_argument(&self) -> bool

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

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

impl Eq for Error

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 From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
