Function takeInt [src]

Asserts the buffer was initialized with a capacity at least @bitSizeOf(T) / 8.

Prototype

pub inline fn takeInt(r: *Reader, comptime T: type, endian: std.builtin.Endian) Error!T

Parameters

r: *ReaderT: typeendian: std.builtin.Endian

Possible Errors

EndOfStream

ReadFailed

See the Reader implementation for detailed diagnostics.

Example

 test takeInt {
    var r: Reader = .fixed(&.{ 0x12, 0x34, 0x56 });
    try testing.expectEqual(0x1234, try r.takeInt(u16, .big));
    try testing.expectError(error.EndOfStream, r.takeInt(u16, .little));
}

Source

  pub inline fn takeInt(r: *Reader, comptime T: type, endian: std.builtin.Endian) Error!T {
    const n = @divExact(@typeInfo(T).int.bits, 8);
    return std.mem.readInt(T, try r.takeArray(n), endian);
}
