Enum TupleLenAst 

#[non_exhaustive]
pub enum TupleLenAst {
    Some,
    Dynamic,
    Ident,
}

Parsed tuple length.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Some

Length placeholder (_). Corresponds to any single length.

Dynamic

Dynamic tuple length. This length is implicit, as in [Num]. As such, it has an empty span.

Ident

Reference to a length; for example, N in [Num; N].

Trait Implementations

impl Clone for TupleLenAst

fn clone(&self) -> TupleLenAst

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TupleLenAst

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

Formats the value using the given formatter.

impl PartialEq for TupleLenAst

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