Trait StaticSize 

pub trait StaticSize {
    const MAX_SIZE: usize;
    const PACKED_MAX_SIZE: usize = Self::MAX_SIZE;
}

Available on crate feature static-size and (crate features alloc or derive or serde or static-size or std or zero-copy) only.

A trait that calculates the upper bound of a type’s serialized size as a const value.

Required Associated Constants

const MAX_SIZE: usize

The maximum possible serialized size in bytes (no bit-packing).

Provided Associated Constants

const PACKED_MAX_SIZE: usize = Self::MAX_SIZE

The maximum possible serialized size in bytes when bit-packing is enabled.

For types with #[bincode(bits = N)] fields this is typically smaller than MAX_SIZE because consecutive bit-packed fields share bytes. Types that have no bit-packed fields default to MAX_SIZE.

Dyn Compatibility

This trait is not dyn compatible.

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