Implementations

impl SectionHeader

pub fn read<TReader: Read>(reader: &mut TReader) -> Result<(u32, SectionHeader)>

Attempts to read a BPX Section Header from an IO backend.

Arguments

• reader: the IO backend to read from.

returns: Result<(u32, SectionHeader), Error>

Errors

Returns an Error if the data could not be read from the IO backend.

pub fn new() -> SectionHeader

Creates a new empty BPX Section Header.

pub fn is_huge_section(&self) -> bool

Checks if this section is huge (greater than 100Mb).

pub fn get_checksum(&self) -> u32

Computes the checksum for this header.

pub fn write<TWriter: Write>(&self, writer: &mut TWriter) -> Result<()>

Attempts to write this header to an IO backend.

Arguments

• writer: the IO backend to write to.

returns: Result<(), Error>

Errors

Returns an Error if the data could not be written to the IO backend.
