arsd.declarativeloader

A declarative file/stream loader/saver. You define structs with a handful of annotations, this read and writes them to/from files.

Members

Enums

BigEndian enum BigEndian
LittleEndian enum LittleEndian
NotSaved enum NotSaved: The marked field is not in the actual file
VariableLength enum VariableLength: @VariableLength indicates the value is saved in a MIDI like format

Functions

MustBe auto MustBe(T t): Insists the field must be a certain value, like for magic numbers
Tag auto Tag(T t): @Tagged!Field indicates a tagged union. Each struct within should have @Tag(X) which is a value of Field
loadFrom int loadFrom(T t, Range r, bool assumeBigEndian): input range of ubytes...

Structs

NumBytes struct NumBytes(alias field)
NumElements struct NumElements(alias field): @NumBytes!Field or @NumElements!Field controls length of embedded arrays
Tagged struct Tagged(alias field): @Tagged!Field indicates a tagged union. Each struct within should have @Tag(X) which is a value of Field
presentIf struct presentIf: For example @presentIf("version >= 2") int addedInVersion2;
