block_type: u32

block_len1: u32

linktype: Linktype

reserved: u16

snaplen: u32

options: Vec<PcapNGOption<'a>>

block_len2: u32

if_tsresol: u8

if_tsoffset: i64

Implementations

impl InterfaceDescriptionBlock<'_>

pub fn ts_resolution(&self) -> Option<u64>

Decode the interface time resolution, in units per second

Return the resolution, or None if the resolution is invalid (for ex. greater than 2^64)

pub fn ts_offset(&self) -> i64

Return the interface timestamp offset

pub fn if_name(&self) -> Option<Result<&str, PcapNGOptionError>>

Return the if_name option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_description(&self) -> Option<Result<&str, PcapNGOptionError>>

Return the if_description option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_os(&self) -> Option<Result<&str, PcapNGOptionError>>

Return the if_os option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_ipv4addr( &self, ) -> Option<Result<Vec<(Ipv4Addr, Ipv4Addr)>, PcapNGOptionError>>

Return the if_ipv4addr option values, if present

This option can be multi-valued.

Returns None if option is not present, Some(Ok(Vec)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

Each item of the Vec is a pair (IPv4Addr, IPv4Mask)

pub fn if_ipv6addr( &self, ) -> Option<Result<Vec<(Ipv6Addr, u8)>, PcapNGOptionError>>

Return the if_ipv6addr option values, if present

This option can be multi-valued.

Returns None if option is not present, Some(Ok(Vec)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

Each item of the Vec is a pair (IPv6Addr, PrefixLen)

pub fn if_macaddr(&self) -> Option<Result<&[u8], PcapNGOptionError>>

Return the if_macaddr option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_euiaddr(&self) -> Option<Result<&[u8], PcapNGOptionError>>

Return the if_euiaddr option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_speed(&self) -> Option<Result<u64, PcapNGOptionError>>

Return the if_speed option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_tsresol(&self) -> Option<Result<u8, PcapNGOptionError>>

Return the if_tsresol option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_filter(&self) -> Option<Result<&str, PcapNGOptionError>>

Return the if_filter option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid

pub fn if_tsoffset(&self) -> Option<Result<i64, PcapNGOptionError>>

Return the if_tsoffset option value, if present

If the option is present multiple times, the first value is returned.

Returns None if option is not present, Some(Ok(value)) if the value is present and valid, or Some(Err(_)) if value is present but invalid
