Implementations

impl PciSpecializedHeader

pub fn length_of_subheader(header_type: u8) -> Option<usize>

Returns the length of the “sub-header” for the specified header_type.

pub fn read_subheader( header_type: u8, bytes: &[u8], includes_common_header: bool, ) -> Result<Self, PciInfoError>

Reads the data of the sub-header from a memory buffer.

• bytes : specifies the slice containing the data to be read
• includes_common_header : true if the slice starts at the beginning of the common header, false if the slice contains only the sub-header data
