Struct RangeError 

pub struct RangeError {
    pub label: &'static str,
    pub values: [u64; 2],
}

A value a checked constructor refused for lying outside the range its type takes, such as an object instance past 4,194,303 (#1646).

Like DecodeError it carries a static label and up to two numbers, formatted when displayed. It displays as value out of range: {label}.

Fields

label: &'static str

What is out of range, such as "instance number {} exceeds max 4194303".

values: [u64; 2]

The numbers the label’s placeholders stand for, in order; a slot with no placeholder is 0.

Implementations

impl RangeError

pub const fn new(label: &'static str) -> Self

A refusal described by label.

pub const fn with_value(self, value: u64) -> Self

The same refusal, with the number the label’s one placeholder stands for.

pub const fn with_values(self, first: u64, second: u64) -> Self

The same refusal, with the numbers the label’s two placeholders stand for.

pub fn message(&self) -> impl Display + '_

The label with its numbers, without the value out of range: prefix.

Trait Implementations

impl Eq for RangeError

impl Error for RangeError

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.

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RangeError

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

Equality operator ==.

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

Inequality operator !=.
