Enum ParseError 

pub enum ParseError {
    Empty,
    MissingUnit {
        input: String,
    },
    InvalidNumber {
        input: String,
        number: String,

}

Why a quantity string could not be read.

Variants

Empty

The input was empty or all whitespace.

MissingUnit

The magnitude was there but the unit was missing.

Fields

input: String

The offending input.

InvalidNumber

The magnitude was not a decimal number.

Fields

input: String

The offending input.

number: String

The part that should have been a number.

UnknownUnit

The unit is not one this dimension knows.

Fields

dimension: &'static str

Which dimension was being parsed.

unit: String

The unrecognised unit.

input: String

The offending input.

NotFinite

The magnitude parsed but is infinite or NaN.

Fields

input: String

The offending input.

OutOfRange

The quantity is outside the accepted sign range.

Fields

input: String

The offending input.

requirement: &'static str

The accepted sign range.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Eq for ParseError

impl Error for ParseError

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 ParseError

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