Trait ToIpv4Netmask 

pub trait ToIpv4Netmask {
    // Required method
    fn prefix(&self) -> Result<u8>;

    // Provided method
    fn netmask(&self) -> Result<Ipv4Addr> { ... }
}

Available on Windows, or Linux and non-target_env=ohos, or macOS, or FreeBSD, or OpenBSD, or NetBSD only.

Trait for converting various types into an IPv4 netmask (prefix length).

Required Methods

fn prefix(&self) -> Result<u8>

Returns the prefix length (i.e., the number of consecutive 1s in the netmask).

Provided Methods

fn netmask(&self) -> Result<Ipv4Addr>

Computes the IPv4 netmask based on the prefix length.
