Implementations

impl TokenKind

pub const fn is_eof(self) -> bool

Returns true if this is an end of file token.

pub const fn is_any_newline(self) -> bool

Returns true if this is either a newline or non-logical newline token.

pub fn is_keyword(self) -> bool

Returns true if the token is a keyword (including soft keywords).

See also is_soft_keyword, is_non_soft_keyword.

pub fn is_soft_keyword(self) -> bool

Returns true if the token is strictly a soft keyword.

See also is_keyword, is_non_soft_keyword.

pub fn is_non_soft_keyword(self) -> bool

Returns true if the token is strictly a non-soft keyword.

See also is_keyword, is_soft_keyword.

pub const fn is_operator(self) -> bool

pub const fn is_singleton(self) -> bool

Returns true if this is a singleton token i.e., True, False, or None.

pub const fn is_trivia(&self) -> bool

Returns true if this is a trivia token i.e., a comment or a non-logical newline.

pub const fn is_comment(&self) -> bool

Returns true if this is a comment token.

pub const fn is_arithmetic(self) -> bool

pub const fn is_bitwise_or_shift(self) -> bool

pub const fn is_unary_arithmetic_operator(self) -> bool

Returns true if the current token is a unary arithmetic operator.

pub const fn is_interpolated_string_end(self) -> bool

pub const fn as_unary_arithmetic_operator(self) -> Option<UnaryOp>

Returns the UnaryOp that corresponds to this token kind, if it is a unary arithmetic operator, otherwise return None.

Use as_unary_operator to match against any unary operator.

pub const fn as_unary_operator(self) -> Option<UnaryOp>

Returns the UnaryOp that corresponds to this token kind, if it is a unary operator, otherwise return None.

Use as_unary_arithmetic_operator to match against only an arithmetic unary operator.

pub const fn as_bool_operator(self) -> Option<BoolOp>

Returns the BoolOp that corresponds to this token kind, if it is a boolean operator, otherwise return None.

pub const fn as_binary_operator(self) -> Option<Operator>

Returns the binary Operator that corresponds to the current token, if it’s a binary operator, otherwise return None.

Use as_augmented_assign_operator to match against an augmented assignment token.

pub const fn as_augmented_assign_operator(self) -> Option<Operator>

Returns the Operator that corresponds to this token kind, if it is an augmented assignment operator, or None otherwise.

Trait Implementations

impl Clone for TokenKind

fn clone(&self) -> TokenKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenKind

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

Formats the value using the given formatter.

impl Display for TokenKind

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

Formats the value using the given formatter.

fn from(op: BoolOp) -> Self

Converts to this type from the input type.

impl From<Operator> for TokenKind

fn from(op: Operator) -> Self

Converts to this type from the input type.

impl From<UnaryOp> for TokenKind

fn from(op: UnaryOp) -> Self

Converts to this type from the input type.

impl Hash for TokenKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TokenKind

fn cmp(&self, other: &TokenKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TokenKind

fn eq(&self, other: &TokenKind) -> 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 PartialOrd for TokenKind

fn partial_cmp(&self, other: &TokenKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
