Implementations

impl<'a> Segment<'a>

pub fn new(ctx: Ctx, sections: &'a [u8]) -> Self

Create a new, blank segment, with cmd either LC_SEGMENT_64, or LC_SEGMENT, depending on ctx. NB You are responsible for providing a correctly marshalled byte array as the sections. You should not use this for anything other than writing.

pub fn name(&self) -> Result<&str>

Get the name of this segment

pub fn sections(&self) -> Result<Vec<(Section, SectionData<'a>)>>

Get the sections from this segment, erroring if any section couldn’t be retrieved

pub fn from_32( bytes: &'a [u8], segment: &SegmentCommand32, offset: usize, ctx: Ctx, ) -> Result<Self, Error>

Convert the raw C 32-bit segment command to a generalized version

pub fn from_32_lossy( bytes: &'a [u8], segment: &SegmentCommand32, offset: usize, ctx: Ctx, ) -> Result<Self, Error>

Convert the raw C 32-bit segment command to a generalized version

pub fn from_64( bytes: &'a [u8], segment: &SegmentCommand64, offset: usize, ctx: Ctx, ) -> Result<Self, Error>

Convert the raw C 64-bit segment command to a generalized version

pub fn from_64_lossy( bytes: &'a [u8], segment: &SegmentCommand64, offset: usize, ctx: Ctx, ) -> Result<Self, Error>

Convert the raw C 64-bit segment command to a generalized version
