Implementations§

source§

impl Number

source

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.

source

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.

source

pub fn is_f64(&self) -> bool

Returns true if the Number can be represented by f64.

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

source

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

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

source

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

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

source

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

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

source

pub fn is_nan(&self) -> bool

Returns true if this value is NaN and false otherwise.

source

pub fn is_infinite(&self) -> bool

Returns true if this value is positive infinity or negative infinity and false otherwise.

source

pub fn is_finite(&self) -> bool

Returns true if this number is neither infinite nor NaN.
