Struct apollo_compiler::ast::IntValue

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

Implementations

impl IntValue

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

Constructs from a string matching the IntValue grammar specification

To convert an i32, use from or into instead.

pub fn as_str(&self) -> &str

Returns the string representation

pub fn try_to_i32(&self) -> Result<i32, ParseIntError>

Converts to i32, returning an error on overflow

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

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

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

An IntValue signals integer syntax was used, but is also valid in contexts where a Float is expected.

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

Trait Implementations

impl Clone for IntValue

fn clone(&self) -> IntValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IntValue

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

Formats the value using the given formatter.

impl Display for IntValue

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

Formats the value using the given formatter.

impl From<i32> for IntValue

fn from(value: i32) -> Self

Converts to this type from the input type.

impl Hash for IntValue

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 IntValue

fn eq(&self, other: &IntValue) -> 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.
