Enum CreateMessageError 

pub enum CreateMessageError {
    InvalidNumber {
        number: usize,
        n: usize,
    },
    WithoutNumber {
        number: usize,
        n: usize,
    },
    EmptyPlaceholder,
}

Represents errors that can occur when working with constant messages.

This enum provides detailed error information for invalid or missing argument numbers in constant messages.

Variants

InvalidNumber

Error indicating that an argument number is out of the allowed range.

This error occurs when an argument number is provided that is not within the valid range of 0 to N-1, where N is the number of expected arguments.

Fields

number: usize

n: usize

WithoutNumber

Error indicating that a required argument number is missing.

This error occurs when an expected argument number is not found within the valid range of 0 to N-1, where N is the number of expected arguments.

Fields

number: usize

n: usize

EmptyPlaceholder

Error indicating that a placeholder is empty.

This error occurs when a placeholder is empty. This can happen when a placeholder is found without a number.

Implementations

impl CreateMessageError

pub const fn panic(&self) -> !

Trait Implementations

impl Clone for CreateMessageError

fn clone(&self) -> CreateMessageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreateMessageError

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

Formats the value using the given formatter.

impl Display for CreateMessageError

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

Formats the value using the given formatter.

impl Error for CreateMessageError

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 CreateMessageError

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