Implementations

impl Width

pub fn holds(self, n: i64) -> bool

pub fn narrowest<T>(min: T, max: T) -> Width

where T: Into<i64>,

The narrowest width that holds min, max and every integer between. Every width holds the empty range, where min is above max.

pub fn below(bound: usize) -> Width

The narrowest width that holds every position below bound.

pub fn join(self, other: Width) -> Width

The narrowest width that holds the integers of both widths.

pub fn wider(self) -> Option<Width>

The next wider width, if there is one.

pub fn float(self, limit: FloatWidth) -> FloatWidth

The float width that integers of this width become beside a float, no wider than limit. With a limit of f64, this is NumPy’s rule: the narrowest float that holds each of them exactly. That’s f16 for u8, f32 for i16 and f64 for i32. i64 also gives f64, which holds its integers exactly only up to 2^53. A session whose default float is narrower passes that width as limit.
