Struct WasiMemoryLayout

pub struct WasiMemoryLayout {
    pub stack_upper: u64,
    pub stack_lower: u64,
    pub guard_size: u64,
    pub stack_size: u64,
    pub tls_base: Option<u64>,
}

Represents the memory layout of the parts that the thread itself uses Represents the memory layout of the parts that the thread itself uses

Fields

stack_upper: u64

This is the top part of the stack (stacks go backwards)

stack_lower: u64

This is the bottom part of the stack (anything more below this is a stack overflow)

guard_size: u64

Piece of memory that is marked as none readable/writable so stack overflows cause an exception TODO: This field will need to be used to mark the guard memory as inaccessible

stack_size: u64

Total size of the stack

tls_base: Option<u64>

Pointer to the thread’s TLS (Thread Local Storage) memory, only filled in when it’s known. This is mainly used by the dynamic linker; especially so since we can’t even find the TLS area for a non-PIE module that doesn’t export its __tls_base. For DL modules, this is the TLS base of the main module.

Trait Implementations

impl Clone for WasiMemoryLayout

fn clone(&self) -> WasiMemoryLayout

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasiMemoryLayout

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

Formats the value using the given formatter.

impl Default for WasiMemoryLayout

fn default() -> WasiMemoryLayout

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WasiMemoryLayout

fn deserialize<__D>( __deserializer: __D, ) -> Result<WasiMemoryLayout, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ArchivedJournalWasiMemoryLayout> for WasiMemoryLayout

fn from(value: &ArchivedJournalWasiMemoryLayout) -> WasiMemoryLayout

Converts to this type from the input type.

impl From<JournalWasiMemoryLayout> for WasiMemoryLayout

fn from(value: JournalWasiMemoryLayout) -> WasiMemoryLayout

Converts to this type from the input type.

impl From<WasiMemoryLayout> for JournalWasiMemoryLayout

fn from(value: WasiMemoryLayout) -> JournalWasiMemoryLayout

Converts to this type from the input type.

impl Hash for WasiMemoryLayout

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

where __H: Hasher,

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 WasiMemoryLayout

fn eq(&self, other: &WasiMemoryLayout) -> 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 Serialize for WasiMemoryLayout

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
