Struct SymbolRef 

pub struct SymbolRef<'a> { /* private fields */ }

A reference to a fully resolved symbol. Like Symbol (a fully resolved symbol with a static lifetime), a SymbolRef may have known or undefined text (i.e. $0).

Implementations

impl<'a> SymbolRef<'a>

pub fn text(&self) -> Option<&'a str>

If this symbol has known text, returns Some(&str). Otherwise, returns None.

pub fn with_unknown_text() -> Self

Constructs a SymbolRef with unknown text.

pub fn with_text(text: &'a str) -> SymbolRef<'a>

Constructs a SymbolRef with the specified text.

pub fn to_owned(self) -> Symbol

pub fn expect_text(&self) -> IonResult<&'a str>

Trait Implementations

impl Borrow<str> for SymbolRef<'_>

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl<'a> Clone for SymbolRef<'a>

fn clone(&self) -> SymbolRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for SymbolRef<'a>

impl Debug for SymbolRef<'_>

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

Formats the value using the given formatter.

impl<'a> Eq for SymbolRef<'a>

impl<'a> From<&'a Symbol> for SymbolRef<'a>

fn from(symbol: &'a Symbol) -> Self

Converts to this type from the input type.

impl<'a> From<&'a str> for SymbolRef<'a>

fn from(text: &'a str) -> Self

Converts to this type from the input type.

impl From<SymbolRef<'_>> for Value

fn from(sym_val: SymbolRef<'_>) -> Self

Converts to this type from the input type.

impl<'a> From<SymbolRef<'a>> for Symbol

fn from(symbol_ref: SymbolRef<'a>) -> Self

Converts to this type from the input type.

impl Hash for SymbolRef<'_>

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<'a> Ord for SymbolRef<'a>

fn cmp(&self, other: &SymbolRef<'a>) -> 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<'a> PartialEq for SymbolRef<'a>

fn eq(&self, other: &SymbolRef<'a>) -> 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<A> PartialEq<A> for SymbolRef<'_>

where A: AsSymbolRef,

fn eq(&self, other: &A) -> 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<'a> PartialOrd for SymbolRef<'a>

fn partial_cmp(&self, other: &SymbolRef<'a>) -> 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.
