Functions

compare

Compares two values with the natural ordering:

  • native types are compared identically to < and other operators
  • complex types
  • Structs and vectors - are compared lexicographically - first field/element is compared first, and if equal we proceed to the next.
  • enum’s are compared first by their variant, and if equal - they are compared as structs are.
public fun compare<T>(first: &T, second: &T): cmp::Ordering
Implementation 
native public fun compare<T>(first: &T, second: &T): Ordering;

is_eq

public fun is_eq(self: &cmp::Ordering): bool
Implementation 
public fun is_eq(self: &Ordering): bool {
    self is Ordering::Equal
}

is_ne

public fun is_ne(self: &cmp::Ordering): bool
Implementation 
public fun is_ne(self: &Ordering): bool {
    !(self is Ordering::Equal)
}

is_lt

public fun is_lt(self: &cmp::Ordering): bool
Implementation 
public fun is_lt(self: &Ordering): bool {
    self is Ordering::Less
}

is_le

public fun is_le(self: &cmp::Ordering): bool
Implementation 
public fun is_le(self: &Ordering): bool {
    !(self is Ordering::Greater)
}

is_gt
