pub trait MultiValueConstLength {
const MULTI_VALUE_CONST_LEN: usize;
}Expand description
Indicates that a multi-value has a fixed (constant) number of single items contained.
This applies to:
- single items
- multi-value tuples
Required Associated Constants§
Sourceconst MULTI_VALUE_CONST_LEN: usize
const MULTI_VALUE_CONST_LEN: usize
The fixed (constant) number of single items contained a multi-value.
Its value is:
- for single items: 1,
- for multi-value tuples: the sum of the fixed lengths of their items, if applicable.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
