Struct MemoryInterval

pub struct MemoryInterval {
    pub offset: u32,
    pub size: u32,
}

Interval in wasm program memory.

Fields

offset: u32

Interval offset in bytes.

size: u32

Interval size in bytes.

Implementations

impl MemoryInterval

pub fn to_bytes(&self) -> [u8; 8]

Convert MemoryInterval to [u8; 8] bytes. 0..4 - offset 4..8 - size

pub fn try_from_bytes(bytes: &[u8]) -> Result<Self, &'static str>

Convert [u8; 8] bytes to MemoryInterval. 0..4 - offset 4..8 - size

Trait Implementations

impl Clone for MemoryInterval

fn clone(&self) -> MemoryInterval

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryInterval

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

Formats the value using the given formatter.

impl Decode for MemoryInterval

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for MemoryInterval

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<(u32, u32)> for MemoryInterval

fn from(val: (u32, u32)) -> Self

Converts to this type from the input type.

impl From<MemoryInterval> for (u32, u32)

fn from(val: MemoryInterval) -> Self

Converts to this type from the input type.

impl PartialEq for MemoryInterval

fn eq(&self, other: &MemoryInterval) -> 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.
