Enum Atomicity

pub enum Atomicity {
    Atomic,
    CompoundAtomic,
    NonAtomic,
}

The current atomicity of a ParserState.

Variants

Atomic

prevents implicit whitespace: inside an atomic rule, the tilde ~ means “immediately followed by”, and repetition operators (asterisk * and plus sign +) have no implicit separation. In addition, all other rules called from an atomic rule are also treated as atomic. (interior matching rules are silent)

CompoundAtomic

The same as atomic, but inner tokens are produced as normal.

NonAtomic

implicit whitespace is enabled

Trait Implementations

impl Clone for Atomicity

fn clone(&self) -> Atomicity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Atomicity

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

Formats the value using the given formatter.

impl PartialEq for Atomicity

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