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)
}
Enables serde with serde/std
.
Enables float-cmp
and num-traits
crates, which provide ::ApproxEq
and ::{cast::ToPrimitive, Zero, One, NumCast}
respectively.
Enables Ryū (龍), for faster float→string conversions.
As of v0.2, an alias for numerical-traits
. This is a breaking change from v0.1, serde no longer default!
As of v0.2, enables all.
