Struct iptables::IPTables

pub struct IPTables {
    pub cmd: &'static str,
    pub has_check: bool,
    pub has_wait: bool,
}

Contains the iptables command and shows if it supports -w and -C options. Use new method to create a new instance of this struct.

Fields

cmd: &'static str

The utility command which must be 'iptables' or 'ip6tables'.

has_check: bool

Indicates if iptables has -C (--check) option

has_wait: bool

Indicates if iptables has -w (--wait) option

Methods

impl IPTables

fn get_policy(&self, table: &str, chain: &str) -> IPTResult<String>

Get the default policy for a table/chain.

fn set_policy(&self, table: &str, chain: &str, policy: &str) -> IPTResult<bool>

Set the default policy for a table/chain.

fn execute(&self, table: &str, command: &str) -> IPTResult<Output>

Executes a given command on the chain. Returns the command output if successful.

fn exists(&self, table: &str, chain: &str, rule: &str) -> IPTResult<bool>

Checks for the existence of the rule in the table/chain. Returns true if the rule exists.

fn chain_exists(&self, table: &str, chain: &str) -> IPTResult<bool>

Checks for the existence of the chain in the table. Returns true if the chain exists.

fn insert(
    &self,
    table: &str,
    chain: &str,
    rule: &str,
    position: i32
) -> IPTResult<bool>

Inserts rule in the position to the table/chain. Returns true if the rule is inserted.

fn insert_unique(
    &self,
    table: &str,
    chain: &str,
    rule: &str,
    position: i32
) -> IPTResult<bool>

Inserts rule in the position to the table/chain if it does not exist. Returns true if the rule is inserted.

fn replace(
    &self,
    table: &str,
    chain: &str,
    rule: &str,
    position: i32
) -> IPTResult<bool>

Replaces rule in the position to the table/chain. Returns true if the rule is replaced.

fn append(&self, table: &str, chain: &str, rule: &str) -> IPTResult<bool>

Appends rule to the table/chain. Returns true if the rule is appended.

fn append_unique(&self, table: &str, chain: &str, rule: &str) -> IPTResult<bool>

Appends rule to the table/chain if it does not exist. Returns true if the rule is appended.

fn append_replace(
    &self,
    table: &str,
    chain: &str,
    rule: &str
) -> IPTResult<bool>

Appends or replaces rule to the table/chain if it does not exist. Returns true if the rule is appended or replaced.

fn delete(&self, table: &str, chain: &str, rule: &str) -> IPTResult<bool>

Deletes rule from the table/chain. Returns true if the rule is deleted.

fn delete_all(&self, table: &str, chain: &str, rule: &str) -> IPTResult<bool>

Deletes all repetition of the rule from the table/chain. Returns true if the rules are deleted.

fn list(&self, table: &str, chain: &str) -> IPTResult<Vec<String>>

Lists rules in the table/chain.

fn list_table(&self, table: &str) -> IPTResult<Vec<String>>

Lists rules in the table.

fn list_chains(&self, table: &str) -> IPTResult<Vec<String>>

Lists the name of each chain in the table.

fn new_chain(&self, table: &str, chain: &str) -> IPTResult<bool>

Creates a new user-defined chain. Returns true if the chain is created.

fn flush_chain(&self, table: &str, chain: &str) -> IPTResult<bool>

Flushes (deletes all rules) a chain. Returns true if the chain is flushed.

fn rename_chain(
    &self,
    table: &str,
    old_chain: &str,
    new_chain: &str
) -> IPTResult<bool>

Renames a chain in the table. Returns true if the chain is renamed.

fn delete_chain(&self, table: &str, chain: &str) -> IPTResult<bool>

Deletes a user-defined chain in the table. Returns true if the chain is deleted.

fn flush_table(&self, table: &str) -> IPTResult<bool>

Flushes all chains in a table. Returns true if the chains are flushed.
