Struct apollo_compiler::ast::FloatValue

pub struct FloatValue(/* private fields */);

Implementations

impl FloatValue

pub fn new_parsed(text: &str) -> Self

Constructs from a string matching the FloatValue grammar specification

To convert an f64, use from or into instead.

pub fn as_str(&self) -> &str

Returns the string representation

pub fn try_to_f64(&self) -> Result<f64, FloatOverflowError>

Converts to a finite f64, returning an error on overflow to infinity

Note: parsing is expected to succeed with a correctly-constructed FloatValue, leaving overflow as the only error case.

Trait Implementations

impl Clone for FloatValue

fn clone(&self) -> FloatValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FloatValue

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

Formats the value using the given formatter.

impl Display for FloatValue

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

Formats the value using the given formatter.

impl From<f64> for FloatValue

fn from(value: f64) -> Self

Converts to this type from the input type.

impl Hash for FloatValue

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 PartialEq for FloatValue

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
