Struct TooLongError 

pub struct TooLongError { /* private fields */ }

Error returned when a string newtype is longer than its len upper bound.

Implementations

impl TooLongError

pub const fn new(max: usize, actual: usize) -> Self

Creates a too-long error.

pub const fn max(&self) -> usize

Returns the maximum accepted length, measured as untrimmed Unicode scalar values.

pub const fn actual(&self) -> usize

Returns the actual length, measured as untrimmed Unicode scalar values.

Trait Implementations

impl Clone for TooLongError

fn clone(&self) -> TooLongError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TooLongError

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

Formats the value using the given formatter.

impl Display for TooLongError

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

Formats the value using the given formatter.

impl Error for TooLongError

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 TooLongError

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