Function byteSwapAllElements [src]

Reverses the byte order of all elements in a slice. Handles structs, unions, arrays, enums, floats, and integers recursively. Useful for converting between little-endian and big-endian representations.

Prototype

pub fn byteSwapAllElements(comptime Elem: type, slice: []Elem) void

Parameters

Elem: typeslice: []Elem

Source

  pub fn byteSwapAllElements(comptime Elem: type, slice: []Elem) void {
    for (slice) |*elem| {
        switch (@typeInfo(@TypeOf(elem.*))) {
            .@"struct", .@"union", .array => byteSwapAllFields(@TypeOf(elem.*), elem),
            .@"enum" => {
                elem.* = @enumFromInt(@byteSwap(@intFromEnum(elem.*)));
            },
            .bool => {},
            .float => |float_info| {
                elem.* = @bitCast(@byteSwap(@as(std.meta.Int(.unsigned, float_info.bits), @bitCast(elem.*))));
            },
            else => {
                elem.* = @byteSwap(elem.*);
            },
        }
    }
}
