Trait SeqLockable 

pub unsafe trait SeqLockable: IntoBytes + Immutable {
    const WRITE_SIZE: WriteSize;
    const HAS_INLINE_SEQUENCE: bool;
    const VMO_NAME: &'static [u8];
}

Types that are safe to be synchronized across address spaces using a Seqlock.

A type implementing this trait can optionally include the sequence as its first field, indicated by HAS_INLINE_SEQUENCE. If it does not, SeqLock will place a u32 atomic sequence number in between the header and value.

Safety

Types implementing this trait guarantee that they can be safely written to shared memory in chunks of WRITE_SIZE without introducing undefined behavior for concurrent readers in other address spaces.

Required Associated Constants

const WRITE_SIZE: WriteSize

The chunk size to use when writing to memory, either 4 or 8 bytes.

const HAS_INLINE_SEQUENCE: bool

Indicates whether the type includes the u32 sequence as its first field.

const VMO_NAME: &'static [u8]

Name used to identify the VMO for debugging.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
