Implementations

impl<'a> PcapNGOption<'a>

pub fn value(&self) -> &[u8]

Return a reference to the option value, as raw bytes (not related to the len field)

pub fn as_bytes(&self) -> Option<&[u8]>

Return a reference to the option value, using the len field to limit it, or None if length is invalid

pub fn as_i32_le(&self) -> Option<i32>

Return the option value interpreted as i32, or None

Option data length and declared must be exactly 4 bytes

pub fn as_u32_le(&self) -> Option<u32>

Return the option value interpreted as u32, or None

Option data length and declared must be exactly 4 bytes

pub fn as_i64_le(&self) -> Option<i64>

Return the option value interpreted as i64, or None

Option data length and declared must be exactly 8 bytes

pub fn as_u64_le(&self) -> Option<u64>

Return the option value interpreted as u64, or None

Option data length and declared must be exactly 8 bytes

Trait Implementations

impl<'a> Debug for PcapNGOption<'a>

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

Formats the value using the given formatter.

impl<'a> ToVec for PcapNGOption<'a>

Available on crate feature serialize only.

fn to_vec_raw(&self) -> Result<Vec<u8>, GenError>

Serialize to bytes representation (little-endian). Do not check values

fn to_vec(&mut self) -> Result<Vec<u8>, GenError>

Serialize to bytes representation (little-endian). Check values and fix all fields before serializing.

fn fix(&mut self)

Check and correct all fields: use magic, fix lengths fields and other values if possible.
