Methods

impl Syntax

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Syntax.

pub fn from_i32(value: i32) -> Option<Syntax>

Converts an i32 to a Syntax, or None if value is not a valid variant.

Trait Implementations

impl Clone for Syntax

fn clone(&self) -> Syntax

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Syntax

impl Debug for Syntax

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

Formats the value using the given formatter.

impl Default for Syntax

fn default() -> Syntax

Returns the "default value" for a type.

impl Eq for Syntax

impl From<Syntax> for i32

fn from(value: Syntax) -> i32

Performs the conversion.

impl Hash for Syntax

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,

impl Ord for Syntax

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Syntax> for Syntax

fn eq(&self, other: &Syntax) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Syntax> for Syntax

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

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

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