Struct Number

pub struct Number { /* private fields */ }

Represents an HCL number.

Implementations

impl Number

pub fn from_f64(f: f64) -> Option<Number>

Creates a new Number from a f64. Returns None if the float is infinite or NaN.

Example

assert!(Number::from_f64(42.0).is_some());
assert!(Number::from_f64(f64::NAN).is_none());
assert!(Number::from_f64(f64::INFINITY).is_none());
assert!(Number::from_f64(f64::NEG_INFINITY).is_none());

pub fn as_f64(&self) -> Option<f64>

Represents the Number as f64 if possible. Returns None otherwise.

pub fn as_i64(&self) -> Option<i64>

If the Number is an integer, represent it as i64 if possible. Returns None otherwise.

pub fn as_u64(&self) -> Option<u64>

If the Number is an integer, represent it as u64 if possible. Returns None otherwise.

pub fn is_f64(&self) -> bool

Returns true if the Number is a float.

For any Number on which is_f64 returns true, as_f64 is guaranteed to return the float value.

pub fn is_i64(&self) -> bool

Returns true if the Number is an integer between i64::MIN and i64::MAX.

For any Number on which is_i64 returns true, as_i64 is guaranteed to return the integer value.

pub fn is_u64(&self) -> bool

Returns true if the Number is an integer between zero and u64::MAX.

For any Number on which is_u64 returns true, as_u64 is guaranteed to return the integer value.
