A dynamically-sized array of bits.
|
|
|
|
The Bit Array can be used in several ways:
|
|
|
|
By default you don't need to instantiate a `Bit_Array`.
|
|
Example:
|
|
package test
|
|
|
|
import "core:fmt"
|
|
import ba "core:container/bit_array"
|
|
|
|
main :: proc() {
|
|
bits: ba.Bit_Array
|
|
|
|
// returns `true`
|
|
fmt.println(ba.set(&bits, 42))
|
|
|
|
// returns `false`, `false`, because this Bit Array wasn't created to allow negative indices.
|
|
was_set, was_retrieved := ba.get(&bits, -1)
|
|
fmt.println(was_set, was_retrieved)
|
|
ba.destroy(&bits)
|
|
}
|
|
|
|
A `Bit_Array` can optionally allow for negative indices, if the minimum value was given during creation.
|
|
Example:
|
|
package test
|
|
|
|
import "core:fmt"
|
|
import ba "core:container/bit_array"
|
|
|
|
main :: proc() {
|
|
Foo :: enum int {
|
|
Negative_Test = -42,
|
|
Bar = 420,
|
|
Leaves = 69105,
|
|
}
|
|
|
|
bits := ba.create_from_enum(Foo)
|
|
defer ba.destroy(bits)
|
|
|
|
assert(bits.bias == int(Foo.Negative_Test))
|
|
assert(bits.length == abs(int(min(Foo))) + int(max(Foo)))
|
|
|
|
fmt.printfln("Set(Bar): %v", ba.set(bits, Foo.Bar))
|
|
fmt.printfln("Get(Bar): %v", ba.get(bits, Foo.Bar))
|
|
fmt.printfln("Set(Negative_Test): %v", ba.set(bits, Foo.Negative_Test))
|
|
fmt.printfln("Get(Leaves): %v", ba.get(bits, Foo.Leaves))
|
|
fmt.printfln("Get(Leaves): %v", ba.unsafe_get(bits, Foo.Leaves))
|
|
fmt.printfln("Get(Negative_Test): %v", ba.get(bits, Foo.Negative_Test))
|
|
fmt.printfln("Unset(Negative_Test): %v", ba.unset(bits, Foo.Negative_Test))
|
|
assert(ba.get(bits, Foo.Negative_Test) == false)
|
|
}
|
