Trait IoKnownSize 

pub trait IoKnownSize: Io {
    const MIN_SIZE: usize;

    // Provided method
    fn io_addr_assert<U>(&self, offset: usize) -> usize { ... }
}

Trait for types with a known size at compile time.

This trait is implemented by I/O backends that have a compile-time known size, enabling the use of infallible I/O accessors with compile-time bounds checking.

Types implementing this trait can use the infallible methods in Io trait (e.g., read8, write32), which require Self: IoKnownSize bound.

Required Associated Constants

const MIN_SIZE: usize

Minimum usable size of this region.

Provided Methods

fn io_addr_assert<U>(&self, offset: usize) -> usize

Returns the absolute I/O address for a given offset, performing compile-time bound checks.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
