Enum NArgs 

pub enum NArgs {
    Fixed(usize),
    ZeroOrMore,
    OneOrMore,
    Optional,
    AtLeast(usize),
}

How many arguments a positional slot or keyword takes.

In TOML this can be written as:

• integer nargs = 1 → Fixed(1)
• "*" → ZeroOrMore
• "+" → OneOrMore
• "?" → Optional
• "N+" e.g. "2+" → AtLeast(2)

Variants

Fixed(usize)

ZeroOrMore

OneOrMore

Optional

AtLeast(usize)

Trait Implementations

impl Clone for NArgs

fn clone(&self) -> NArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NArgs

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

Formats the value using the given formatter.

impl Default for NArgs

fn default() -> NArgs

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NArgs

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl PartialEq for NArgs

fn eq(&self, other: &NArgs) -> 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 NArgs

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for NArgs

impl StructuralPartialEq for NArgs
