Implementations

impl TokenType

pub fn reserved_word(s: &str) -> Option<Self>

Returns the reserved word token type for the given string, if any.

pub const fn starts_command(self) -> bool

Returns true if this token type starts a compound command.

Trait Implementations

impl Clone for TokenType

fn clone(&self) -> TokenType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenType

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

Formats the value using the given formatter.

impl PartialEq for TokenType

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

impl Copy for TokenType

impl Eq for TokenType

impl StructuralPartialEq for TokenType
