Struct Ipv4Range 

pub struct Ipv4Range {
    pub start_addr: Ipv4Addr,
    pub end_addr: Ipv4Addr,
}

A contiguous range of IPv4 addresses defined by a start and end point.

Both boundaries are inclusive. Stored as two Ipv4Addr values (8 bytes total).

Fields

start_addr: Ipv4Addr

The inclusive starting address of the range.

end_addr: Ipv4Addr

The inclusive ending address of the range.

Implementations

impl Ipv4Range

pub fn new(start: Ipv4Addr, end: Ipv4Addr) -> Result<Self, IpError>

Creates a new Ipv4Range.

Errors

Returns IpError::InvalidRange if start is numerically greater than end.

pub fn to_iter(&self) -> impl Iterator<Item = IpAddr>

Returns an iterator over every IpAddr within the range.

Performance

Iterating over large ranges (e.g., /8) is fast, but collecting the results into a Vec will consume significant memory.

pub fn contains(&self, ip: &Ipv4Addr) -> bool

Checks if the given Ipv4Addr falls within this range (inclusive).

pub fn len(&self) -> u64

Returns the number of IP addresses in the range.

pub fn is_empty(&self) -> bool

Returns true if the range contains no addresses.
