Struct yrs::encoding::varint::Signed

pub struct Signed<T: Sized + Copy> { /* private fields */ }

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: Sized + Copy> Signed<T>

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

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<U>where F: FnOnce(T) -> U, U: Sized + Copy,

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

Trait Implementations

impl<T: Clone + Sized + Copy> Clone for Signed<T>

fn clone(&self) -> Signed<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + Sized + Copy> Debug for Signed<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: PartialEq + Sized + Copy> PartialEq for Signed<T>

fn eq(&self, other: &Signed<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
