integer_or_float v0.3.2

This is a Rust type that holds an integer or a float.

// from src/backing_types.rs
#[cfg(not(feature = "x64-backing-store"))]
pub type f_iof = f32;
#[cfg(not(feature = "x64-backing-store"))]
pub type i_iof = i32;

/// A generic container for an "integer or a float".
pub enum IntegerOrFloat {
    Integer(i_iof),
    Float(f_iof)
}

At first it was just a Rust implementation of the UFO datatype integer or float, which appears all over the UFO spec, but most importantly in the affine matrices used by glyph components.

Now (v0.1.4) it’s generic. You can compile with the experimental feature x64-backing-store to get an IntegerOrFloat defined as such:

pub enum IntegerOrFloat {
    Integer(i64),
    Float(f64)
}

Rather than the default:

pub enum IntegerOrFloat {
    Integer(i32),
    Float(f32)
}

Discretionary features

more-serde

Enables serde with serde/std.

numerical-traits

Enables float-cmp and num-traits crates, which provide ::ApproxEq and ::{cast::ToPrimitive, Zero, One, NumCast} respectively.

faster-strconv

Enables Ryū (龍), for faster float→string conversions.

default

As of v0.2, an alias for numerical-traits. This is a breaking change from v0.1, serde no longer default!

fat

As of v0.2, enables all.
