Implementations

impl Symbol

pub fn is_end(&self) -> bool

pub fn is_empty(&self) -> bool

pub fn is_t(&self) -> bool

pub fn is_nt(&self) -> bool

pub fn to_str<T: SymInfoTable>(&self, symbol_table: Option<&T>) -> String

pub fn to_str_quote<T: SymInfoTable>(&self, symbol_table: Option<&T>) -> String

Converts the symbol to string, using the symbol table if available, and surrounding it with quotes if it’s a string literal.

pub fn to_str_name<T: SymInfoTable>(&self, symbol_table: Option<&T>) -> String

pub fn to_str_ext<T: SymInfoTable>( &self, symbol_table: Option<&T>, ext: &String, ) -> String

Converts the symbol to string, using the symbol table if available.

pub fn to_macro_item(&self) -> String

Converts to symbols used in sym! and other related macros.

Trait Implementations

impl Clone for Symbol

fn clone(&self) -> Symbol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Symbol

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

Formats the value using the given formatter.

impl Default for Symbol

fn default() -> Symbol

Returns the “default value” for a type.

impl Display for Symbol

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

Formats the value using the given formatter.

impl From<Symbol> for OpCode

fn from(value: Symbol) -> Self

Converts to this type from the input type.

impl Hash for Symbol

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 Symbol

fn cmp(&self, other: &Symbol) -> 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.

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

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 Symbol

fn eq(&self, other: &Symbol) -> 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 Symbol

fn partial_cmp(&self, other: &Symbol) -> 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.
