38. Boost package for array manipulation¶
The array_boost module implements collection of array manipulation routines.
All functions and symbols are in “array_boost” module, use require to get access to it.
require daslib/array_boost
38.1. Temporary arrays¶
-
temp_array(arr: auto implicit ==const)¶
temp_array returns auto
Warning
This is unsafe operation.
argument |
argument type |
|---|---|
arr |
auto implicit! |
Creates temporary array from the given object. Important requirements are:
object memory is linear
each element follows the next one directly, with the stride equal to size of the element
object memory does not change within the lifetime of the returned array
-
temp_array(arr: auto const implicit ==const)
temp_array returns auto
Warning
This is unsafe operation.
argument |
argument type |
|---|---|
arr |
auto const implicit! |
Creates temporary array from the given object. Important requirements are:
object memory is linear
each element follows the next one directly, with the stride equal to size of the element
object memory does not change within the lifetime of the returned array
-
temp_array(data: auto? ==const; lenA: int const; a: auto(TT) const)
temp_array returns array<TT>
Warning
This is unsafe operation.
argument |
argument type |
|---|---|
data |
auto?! |
lenA |
int const |
a |
auto(TT) const |
Creates temporary array from the given object. Important requirements are:
object memory is linear
each element follows the next one directly, with the stride equal to size of the element
object memory does not change within the lifetime of the returned array
-
temp_array(data: auto? const ==const; lenA: int const; a: auto(TT) const)
temp_array returns array<TT> const
Warning
This is unsafe operation.
argument |
argument type |
|---|---|
data |
auto? const! |
lenA |
int const |
a |
auto(TT) const |
Creates temporary array from the given object. Important requirements are:
object memory is linear
each element follows the next one directly, with the stride equal to size of the element
object memory does not change within the lifetime of the returned array
38.2. Empty check¶
-
empty(v: auto(VecT) const)¶
empty returns auto
argument |
argument type |
|---|---|
v |
auto(VecT) const |
returns true if ‘v’ has 0 elements. this also implies that length(v) is defined.
38.3. Uncategorized¶
-
array_view(bytes: array<auto(TT)> const ==const; offset: int const; length: int const; blk: block<(view:array<TT> const#):void> const)¶
array_view returns auto
argument |
argument type |
|---|---|
bytes |
array<auto(TT)> const! |
offset |
int const |
length |
int const |
blk |
block<(view:array<TT> const#):void> const |
creates a view of the array, which is a temporary array that is valid only within the block
-
array_view(bytes: array<auto(TT)> ==const; offset: int const; length: int const; blk: block<(var view:array<TT>#):void> const)
array_view returns auto
argument |
argument type |
|---|---|
bytes |
array<auto(TT)>! |
offset |
int const |
length |
int const |
blk |
block<(view:array<TT>#):void> const |
creates a view of the array, which is a temporary array that is valid only within the block
