Latin-1 string — c.String(n)

Fixed-size, NUL-terminated Latin-1 (one byte per character, not UTF-8). The argument n is the byte size of the whole slot (same as sizeof the C array).

@c.struct()
class Tag {
  @c.field(c.String(16))
  name!: string;
}

C equivalent:

typedef struct {
    char name[16]; /* Latin-1 bytes, NUL-terminated within the 16-byte slot */
} Tag;

A value like "Player1" occupies the first 7 bytes ('P' 'l' 'a' 'y' 'e' 'r' '1' '\0'); the rest of the array is unused padding inside the field.
