Provided Associated Constants

const NTH_KINDSET: KindSet = _

The set of Kinds that can start an <an+b> value.

Required Methods

fn peek_odd<I>(p: &Parser<'a, I>, c: Cursor) -> bool

where I: Iterator<Item = Cursor> + Clone,

Returns true if the cursor is the odd keyword.

fn peek_even<I>(p: &Parser<'a, I>, c: Cursor) -> bool

where I: Iterator<Item = Cursor> + Clone,

Returns true if the cursor is the even keyword.

fn build_odd(node: Ident) -> Self

fn build_even(node: Ident) -> Self

fn build_integer(node: Number) -> Self

fn build_anb(a: i32, b: i32, cursors: [Cursor; 4]) -> Self

Provided Methods

fn anb_matches(a: i32, b: i32, index: i32) -> bool

Returns true if the 1-based index is one of the indices selected by an+b.

fn parse_nth<I>(p: &mut Parser<'a, I>) -> Result<Self>

where I: Iterator<Item = Cursor> + Clone,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
