Implementations

impl SpecArg

pub fn usage(&self) -> String

Trait Implementations

impl Clone for SpecArg

fn clone(&self) -> SpecArg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpecArg

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

Formats the value using the given formatter.

impl Default for SpecArg

fn default() -> SpecArg

Returns the “default value” for a type.

impl Display for SpecArg

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

Formats the value using the given formatter.

impl From<&SpecArg> for KdlNode

fn from(arg: &SpecArg) -> Self

Converts to this type from the input type.

impl From<&str> for SpecArg

fn from(input: &str) -> Self

Converts to this type from the input type.

impl FromStr for SpecArg

type Err = UsageErr

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, UsageErr>

Parses a string s to return a value of this type.

impl Hash for SpecArg

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 SpecArg

fn eq(&self, other: &Self) -> 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 Serialize for SpecArg

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
