Struct Segment

pub struct Segment<T: SizeT> {
    pub p_type: SegmentType,
    pub data: Vec<u8>,
    pub offset: T,
    pub virtual_address: T,
    pub physical_address: T,
    pub size: T,
    pub flags: u32,
    pub align: T,
}

A segment, this gets loaded into memory when elf file gets executed

Fields

p_type: SegmentType

Identifies the type of the segment

data: Vec<u8>

Data of this segment

offset: T

Offset of the segment in the file image

virtual_address: T

Virtual address of the segment in memory

physical_address: T

On systems where physical address is relevant, reserved for segment’s physical address

size: T

Size in bytes of the segment in memory. May be 0. May be more then data to pad segment with zeros

flags: u32

Segment-dependent flags. Essentially permissions, specified with SegmentFlags like that:

use orecc_elf::SegmentFlags;
let flags = SegmentFlags::Readable as u32 | SegmentFlags::Executable as u32;
assert_eq!(flags, 0x05);

align: T

0 and 1 specify no alignment. Otherwise should be a positive, integral power of 2. I don’t really know how it works

Trait Implementations

impl<T: Clone + SizeT> Clone for Segment<T>

fn clone(&self) -> Segment<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + SizeT> Debug for Segment<T>

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

Formats the value using the given formatter.

impl<T: Hash + SizeT> Hash for Segment<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: Ord + SizeT> Ord for Segment<T>

fn cmp(&self, other: &Segment<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq + SizeT> PartialEq for Segment<T>

fn eq(&self, other: &Segment<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd + SizeT> PartialOrd for Segment<T>

fn partial_cmp(&self, other: &Segment<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
