Implementations

impl DatumCharClass

pub const fn potential_identifier(&self) -> bool

If this character class is a potential identifier. Note that this can be accessed via DatumChar via DatumChar::deref.

use datum::DatumChar;
assert!(DatumChar::identify('a').expect("not backslash").potential_identifier());

pub const fn numeric_start(&self) -> bool

If this character class starts a number. Note that this can be accessed via DatumChar via DatumChar::deref.

use datum::DatumChar;
assert!(DatumChar::identify('0').expect("not backslash").numeric_start());

pub const fn identify(v: char) -> Option<Self>

Identifies a character. Meta-class characters return None.

Trait Implementations

impl Clone for DatumCharClass

fn clone(&self) -> DatumCharClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatumCharClass

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

Formats the value using the given formatter.

impl PartialEq for DatumCharClass

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