ipv4 and socket addresses

AddrError

Section titled “AddrError”
pub AddrError :: errors {
    bad_format,
    octet_range,
}
  • bad_format: not a dotted-quad a.b.c.d
  • octet_range: an octet was > 255

IpV4

Section titled “IpV4”
pub IpV4 :: struct {
    a: u8,
    b: u8,
    c: u8,
    d: u8,
}

ipv4 address; #derive(Eq) gives a.eq(&b); format prints 127.0.0.1

IpV4.to_net

Section titled “IpV4.to_net”
pub to_net :: fn(self: *Self) -> u32

packed u32 in network byte order, as in sockaddr_in

IpV4.is_loopback

Section titled “IpV4.is_loopback”
pub is_loopback :: fn(self: *Self) -> bool

127.x.x.x

IpV4.is_unspecified

Section titled “IpV4.is_unspecified”
pub is_unspecified :: fn(self: *Self) -> bool

0.0.0.0, “any interface”

IpV4.format

Section titled “IpV4.format”
pub format :: fn(self: *Self, sb: *StringBuilder)

dotted quad into sb

ipv4

Section titled “ipv4”
pub ipv4 :: fn(a: u8, b: u8, c: u8, d: u8) -> IpV4

address from four octets

localhost

Section titled “localhost”
pub localhost :: fn() -> IpV4

127.0.0.1

any

Section titled “any”
pub any :: fn() -> IpV4

0.0.0.0; bind to every interface

broadcast

pub broadcast :: fn() -> IpV4

255.255.255.255, limited broadcast

from_net

Section titled “from_net”
pub from_net :: fn(n: u32) -> IpV4

network-order in_addr -> octets; inverse of to_net

parse

Section titled “parse”
pub parse :: fn(s: []const u8) -> IpV4 ! AddrError

parse a dotted quad

SocketAddr

pub SocketAddr :: struct {
    ip: IpV4,
    port: u16,
}

ipv4 address + port

SocketAddr.format
