Implementations

impl Pages

pub const fn max_value() -> Self

Returns the largest value that can be represented by the Pages type.

This is defined by the WebAssembly standard as 65,536 pages.

pub fn checked_add(self, rhs: Self) -> Option<Self>

Checked addition. Computes self + rhs, returning None if overflow occurred.

pub fn bytes(self) -> Bytes

Calculate number of bytes from pages.

Trait Implementations

impl<T> Add<T> for Pages

where T: Into<Self>,

type Output = Pages

fn add(self, rhs: T) -> Self

Performs the + operation.

impl Archive for Pages

where u32: Archive,
