Enum ParseArgError

pub enum ParseArgError<E> {
    FromStr(E),
    InvalidUtf8,
}

Possible error when parsing certain arguments.

This is used for bridging implementations of FromStr, because they require UTF-8 encoded inputs.

Variants

FromStr(E)

Parsing as implemented by FromStr failed.

InvalidUtf8

The input isn’t UTF-8 encoded.

Trait Implementations

impl<E: Clone> Clone for ParseArgError<E>

fn clone(&self) -> ParseArgError<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Display> Debug for ParseArgError<E>

Debug is implemented via Display in order to make using ? operator in main nice.

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

Formats the value using the given formatter.

impl<E: Display> Display for ParseArgError<E>

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

Formats the value using the given formatter.

impl<E: Display> From<E> for ParseArgError<E>

fn from(error: E) -> Self

Converts to this type from the input type.

impl<E: Hash> Hash for ParseArgError<E>

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<E: PartialEq> PartialEq for ParseArgError<E>

fn eq(&self, other: &ParseArgError<E>) -> 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.
