Struct SectionHeaderBlock

pub struct SectionHeaderBlock<'a> {
    pub block_type: u32,
    pub block_len1: u32,
    pub bom: u32,
    pub major_version: u16,
    pub minor_version: u16,
    pub section_len: i64,
    pub options: Vec<PcapNGOption<'a>>,
    pub block_len2: u32,
}

The Section Header Block (SHB) identifies the beginning of a section of the capture capture file.

The Section Header Block does not contain data but it rather identifies a list of blocks (interfaces, packets) that are logically correlated.

Implementations

impl SectionHeaderBlock<'_>

pub fn big_endian(&self) -> bool

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

Return the shb_hardware 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 shb_os(&self) -> Option<Result<&str, PcapNGOptionError>>

Return the shb_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 shb_userappl(&self) -> Option<Result<&str, PcapNGOptionError>>

Return the shb_userappl 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
