Struct libafl_bolts::shmem::ShMemId

pub struct ShMemId { /* private fields */ }

An id associated with a given shared memory mapping (ShMem), which can be used to establish shared-mappings between proccesses. Id is a file descriptor if you use MmapShMem or AshmemShMem. That means you have to use shmem server to access to the shmem segment from other processes in these cases. On the other hand, id is a unique identifier if you use CommonUnixShMem or Win32ShMem. In these two cases, you can use shmat(id) or OpenFileMappingA(id) to gain access to the shmem

Implementations

impl ShMemId

pub fn from_array(array: &[u8; 20]) -> Self

Create a new id from a fixed-size string/bytes array It should contain a valid cstring.

pub fn try_from_slice(slice: &[u8]) -> Result<Self, Error>

Try to create a new id from a bytes string. The slice must have a length of at least 20 bytes and contain a valid cstring.

pub fn from_int(val: i32) -> Self

Create a new id from an int

pub fn from_string(val: &str) -> Self

Create a new id from a string

pub const fn is_empty(&self) -> bool

Returns true if this ShMemId has an empty backing slice. If this is the case something went wrong, and this ShMemId may not be read from.

pub const fn as_array(&self) -> &[u8; 20]

Get the id as a fixed-length slice

pub fn null_pos(&self) -> usize

Returns the first null-byte in or the end of the buffer

pub fn as_str(&self) -> &str

Returns a str representation of this ShMemId

Trait Implementations

impl AsSlice for ShMemId

type Entry = u8

Type of the entries in this slice

fn as_slice(&self) -> &[u8]

Convert to a slice

impl Clone for ShMemId

fn clone(&self) -> ShMemId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShMemId

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

Formats the value using the given formatter.

impl Default for ShMemId

fn default() -> ShMemId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ShMemId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ShMemId

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

Formats the value using the given formatter.

impl From<ShMemId> for i32

fn from(id: ShMemId) -> i32

Converts to this type from the input type.

impl Hash for ShMemId

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 PartialEq for ShMemId

fn eq(&self, other: &ShMemId) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ShMemId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ShMemId
