Represents an HCL number.
Implementations
sourceimpl Number
impl Number
sourcepub fn from_f64(f: f64) -> Option<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.
use hcl::Number;
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());
sourcepub fn as_f64(&self) -> Option<f64>
pub fn as_f64(&self) -> Option<f64>
Represents the Number
as f64 if possible. Returns None otherwise.
sourcepub fn as_i64(&self) -> Option<i64>
pub fn as_i64(&self) -> Option<i64>
If the Number
is an integer, represent it as i64 if possible. Returns None otherwise.
sourcepub fn as_u64(&self) -> Option<u64>
pub fn as_u64(&self) -> Option<u64>
If the Number
is an integer, represent it as u64 if possible. Returns None otherwise.
sourcepub fn is_f64(&self) -> bool
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.
