duration

time.duration

§
:
orderable
 is
 
[Private constructor]

time.duration -- value representing a duration, i.e., a time span

This is intendend for high precision time specification and measurement, it
uses a time resolution of 1ns.

The maximum value is about 580 years, so this is not intended for use in
calendars that may require time spans exceeding several centuries or millenia,
nor astrological time spans.

Fields

§
nanos
 u64
the duration in nano seconds

Functions

§
 => 
String  
[Redefinition of  Any.as_string]
create a string representation of this duration. The string
representation is not accurate, it consists of at least two
and at most 4 decimal digits followed by a time unit string.

redefines:

this duration in whole days, omitting fractional part
§
 => 
Type  
[Inherited from  Any]
Get the dynamic type of this instance. For value instances `x`, this is
equal to `type_of x`, but for `x` with a `ref` type `x.dynamic_type` gives
the actual runtime type, while `type_of x` results in the static
compile-time type.

There is no dynamic type of a type instance since this would result in an
endless hierarchy of types. So for Type values, dynamic_type is redefined
to just return Type.type.
this duration in whole hours, omitting fractional part
this duration multiplied by n
this duration in micro seconds, omitting fractional part
this duration in milli seconds, omitting fractional part
this duration in whole minutes, omitting fractional part
§
 => 
String  
[Inherited from  Any]
convenience prefix operator to create a string from a value.

This permits usage of `$` as a prefix operator in a similar way both
inside and outside of constant strings: $x and "$x" will produce the
same string.

this duration in whole weeks, omitting fractional part

Type Functions

create duration of n years

NYI: Turn this into a 'postfix' call, see https://fuzion-lang.dev/design/postfix_calls
§
 => 
String  
[Inherited from  Type]
string representation of this type to be used for debugging.

result has the form "Type of '<name>'", but this might change in the future

redefines:

create duration of n days

§
 => 
Type  
[Inherited from  Type]
There is no dynamic type of a type instance since this would result in an
endless hierarchy of types, so dynamic_type is redefined to just return
Type.type here.

§
(a property.equatable.this.type, b property.equatable.this.type)
 => 
bool  
[Inherited from  equatable]
  
[Abstract feature]
equality implements the default equality relation for values of this type.

This relation must be

- reflexive (equality a b),
- symmetric (equality a b = equality b a), and
- transitive ((equality a b && equality b c) : equality a c).

result is true iff 'a' is considered to represent the same abstract value
as 'b'.
create duration of n hours

§
(T 
type
)
 => 
bool  
[Inherited from  Type]
Is this type assignable to a type parameter with constraint `T`?

The result of this is a compile-time constant that can be used to specialize
code for a particular type.

is_of_integer_type(n T : numeric) => T : integer
say (is_of_integer_type 1234) # true
say (is_of_integer_type 3.14) # false

it is most useful in conjunction preconditions or `if` statements as in

pair(a,b T) is

=>

or

val(n T) is

§
 => 
bool  
[Inherited from  equatable]
additional restrictions on when equality is permitted,
e.g., `option T` might require `T : property.equatable`.

§
 => 
String  
[Inherited from  Type]
name of this type, including type parameters, e.g. 'option (list i32)'.
create duration of n ns

§
 => 
String  
[Inherited from  Type]
convenience prefix operator to create a string from a value.

This permits usage of `$` as a prefix operator in a similar way both
inside and outside of constant strings: $x and "$x" will produce the
same string.

NYI: Redefinition allows the type feature to be distinguished from its normal counterpart, see #3913

§
 => 
Type  
[Inherited from  Any]
Get a type as a value.

This is a feature with the effect equivalent to Fuzion's `expr.type` call tail.
It is recommended to use `expr.type` and not `expr.type_value`.

`type_value` is here to show how this can be implemented and to illustrate the
difference to `dynamic_type`.
