Struct ReplaceInfo 

Source 
pub struct ReplaceInfo {
    pub table_id: TableId,
    pub num_entries: usize,
    pub size: usize,
    pub valid_hooks: NfIpHooks,
    pub hook_entry: [c_uint; 5],

Expand description

Metadata passed by iptables when updating a table.

Describes the subsequent buffer of size bytes, containing num_entries Entries that describe chain definitions, rule specifications, and end of input. IPv4 and IPv6 tables have the same metadata but uses different Linux structs: ipt_replace for IPv4, and ip6t_replace for IPv6.

Fields§

§table_id: TableId

The table to be replaced.

§num_entries: usize

Number of entries defined on the table.

§size: usize

Size of entries in bytes.

§valid_hooks: NfIpHooks

Bitmap of which installed chains are on the table.

§hook_entry: [c_uint; 5]

Byte offsets of the first entry of each installed chain.

§underflow: [c_uint; 5]

Byte offsets of the policy of each installed chain.

§num_counters: c_uint

Unused field. Number of counters.
