Implementations§

source§

impl Numeric

source

pub fn validate(self) -> Result<Numeric, Error>

Ensures this value contains a valid value.

Errors

Error::NotANumber is returned if this contains a NaN floating point value.

source

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

Returns this numeric as an i64. If this conversion cannot be done without losing precision or overflowing, None will be returned.

source

pub fn as_i64_lossy(&self, saturating: bool) -> i64

Returns this numeric as an i64, allowing for precision to be lost if the type was not an i64 originally. If saturating is true, the conversion will not allow overflows.

source

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

Returns this numeric as an u64. If this conversion cannot be done without losing precision or overflowing, None will be returned.

source

pub fn as_u64_lossy(&self, saturating: bool) -> u64

Returns this numeric as an u64, allowing for precision to be lost if the type was not an i64 originally. If saturating is true, the conversion will not allow overflows.

source

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

Returns this numeric as an f64. If this conversion cannot be done without losing precision, None will be returned.

source

pub const fn as_f64_lossy(&self) -> f64

Returns this numeric as an f64, allowing for precision to be lost if the type was not an f64 originally.
