pub enum Num {
    Num(u16),
    Arg(u16),
    Next,
}

Implementations

impl Num

fn from_str(s: &str, arg: Option<&str>) -> Self

fn translate(&self, s: &mut String) -> Result

Trait Implementations

impl Clone for Num

fn clone(&self) -> Num

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Num

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

Formats the value using the given formatter.

impl PartialEq<Num> for Num

fn eq(&self, other: &Num) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Num) -> bool

This method tests for !=.

impl Copy for Num

impl StructuralPartialEq for Num

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
