Struct ArgumentError 

pub struct ArgumentError { /* private fields */ }

Argument validation error

Returned when an argument does not satisfy validation conditions.

Features

• Contains detailed error messages
• Implements standard error traits
• Supports conversion from strings

Examples

use prism3_core::lang::argument::ArgumentError;

let error = ArgumentError::new("Invalid argument");
assert_eq!(error.message(), "Invalid argument");

Implementations

impl ArgumentError

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

Create a new argument error

Parameters

• message - Error message

Examples

use prism3_core::lang::argument::ArgumentError;

let error = ArgumentError::new("Value cannot be negative");

pub fn message(&self) -> &str

Get the error message

Returns

Returns a reference to the error message

Trait Implementations

impl Clone for ArgumentError

fn clone(&self) -> ArgumentError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArgumentError

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

Formats the value using the given formatter.

impl Display for ArgumentError

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

Formats the value using the given formatter.

impl Error for ArgumentError

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<&str> for ArgumentError

fn from(message: &str) -> Self

Converts to this type from the input type.

impl From<String> for ArgumentError

fn from(message: String) -> Self

Converts to this type from the input type.

impl PartialEq for ArgumentError

fn eq(&self, other: &ArgumentError) -> 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.
