Struct Signed

pub struct Signed<T>where
    T: Copy,
{ /* private fields */ }

Expand description

Struct which recognizes signed integer values. This special case has been build for Yjs encoding compatibility, which recognizes differences between 0 and -0, which is used in some cases (eg. UIntOptRleDecoder).

Implementations§

§

impl<T> Signed<T>
where T: Copy,

pub fn new(value: T, is_negative: bool) -> Signed<T>

pub fn is_positive(&self) -> bool

Returns true is stored number is a positive value.

pub fn is_negative(&self) -> bool

Returns true is stored number is a negative value (including -0 as a special case).

pub fn value(&self) -> T

Returns a stored value.

pub fn map<F, U>(&self, f: F) -> Signed
where F: FnOnce(T) -> U, U: Copy,

Maps contents of a Signed value container to a new data type, retaining the sign information.
