Enum IndexArg 

pub enum IndexArg {
    Number(usize),
    Field(String),
    Item,
    Wildcard,
}

The idx in [idx].

Only indexing by numeric index, field name or wilcard is permitted. Recursion .. and ranges [start:end:step] are not supported.

Variants

Number(usize)

A number index

Field(String)

An index by name (works just like the dot operator)

Item

Wildcard

Trait Implementations

impl Clone for IndexArg

fn clone(&self) -> IndexArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexArg

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

Formats the value using the given formatter.

impl Display for IndexArg

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

Formats the value using the given formatter.

impl Eq for IndexArg

impl Hash for IndexArg

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 IndexArg

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