Crate js_int
provides JavaScript-interoperable integer types.
JavaScript does not have native integers. Instead it represents all numeric
values with a single Number
type which is represented as an
IEEE 754 floating-point value. Rust's
i64
and u64
types can contain values outside the range of what can be
represented in a JavaScript Number
.
This crate provides the types Int
and UInt
which wrap i64
and u64
,
respectively. These types add bounds checking to ensure the contained value is
within the range representable by a JavaScript Number
. They provide useful
trait implementations to easily convert from Rust's primitive integer types.
This crate requires rustc >= 1.34.2.
This crate is no_std
-compatible with default-features = false
. This will
disable the std
feature, which at the time of writing will only omit the
implementations of std::error::Error
for ParseIntError
and
TryFromIntError
.
(De-)Serialization via serde
is supported via the serde
feature, even
without the std
feature.
Deserialization of Int
and UInt
form values and path parameters for users
of the Rocket web framework version 0.4 are supported via the rocket_04
feature.
