Struct ArgumentError

pub struct ArgumentError<'a> { /* private fields */ }

Error that indicates the byte string input to parse was invalid.

This error can be returned in the following circumstances:

• The input has non-ASCII bytes.
• The input contains a NUL byte.
• The input is the empty byte slice.
• The input only contains +/- signs.
• The given radix does not match a 0x-style prefix.
• Invalid or duplicate +/- signs are in the input.
• Consecutive underscores are present in the input.
• Leading or trailing underscores are present in the input.
• The input contains ASCII alphanumeric bytes that are invalid for the computed radix.

Examples

let result = scolapasta_int_parse::parse("0xBAD", Some(10));
let err = result.unwrap_err();
assert_eq!(err.to_string(), r#"invalid value for Integer(): "0xBAD""#);

Implementations

impl<'a> ArgumentError<'a>

pub const fn subject(self) -> &'a [u8]

Return the subject of parsing that returned this argument error.

Examples

let result = scolapasta_int_parse::parse("0xBAD", Some(10));
let err = result.unwrap_err();
assert!(matches!(err, Error::Argument(err) if err.subject() == "0xBAD".as_bytes()));

Trait Implementations

impl<'a> Clone for ArgumentError<'a>

fn clone(&self) -> ArgumentError<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ArgumentError<'a>

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

Formats the value using the given formatter.

impl<'a> Default for ArgumentError<'a>

fn default() -> ArgumentError<'a>

Returns the “default value” for a type.

impl<'a> Display for ArgumentError<'a>

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

Formats the value using the given formatter.

impl<'a> Error for ArgumentError<'a>

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<'a> From<&'a [u8]> for ArgumentError<'a>

fn from(subject: &'a [u8]) -> Self

Converts to this type from the input type.

impl<'a> From<ArgumentError<'a>> for Error<'a>

fn from(err: ArgumentError<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for ArgumentError<'a>

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<'a> Ord for ArgumentError<'a>

fn cmp(&self, other: &ArgumentError<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for ArgumentError<'a>

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

impl<'a> PartialOrd for ArgumentError<'a>

fn partial_cmp(&self, other: &ArgumentError<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
