Struct IpFilter 

pub struct IpFilter { /* private fields */ }

IP filter for restricting network communication to specific IP ranges using CIDR notation.

Implementations

impl IpFilter

pub const fn new(allowed_networks: Vec<IpNet>) -> Self

Creates a new IP filter with the given CIDR networks.

If the list is empty, all IPs will be allowed.

pub fn from_cidr_string(cidrs: &str) -> Result<Self, AddrParseError>

Creates an IP filter from a comma-separated list of CIDR networks.

Errors

Returns an error if any of the CIDR strings cannot be parsed.

pub const fn allow_all() -> Self

Creates a filter that allows all IPs.

pub fn is_allowed(&self, ip: &IpAddr) -> bool

Checks if the given IP address is allowed by this filter.

Returns true if the filter is empty (allows all) or if the IP is within any of the allowed networks.

pub const fn has_restrictions(&self) -> bool

Returns true if this filter has restrictions (i.e., not allowing all IPs).

pub fn allowed_networks(&self) -> &[IpNet]

Returns the list of allowed networks.

Trait Implementations

impl Clone for IpFilter

fn clone(&self) -> IpFilter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IpFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for IpFilter

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for IpFilter

fn eq(&self, other: &IpFilter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for IpFilter

impl StructuralPartialEq for IpFilter

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
