-- The `max_len` length represents the length of the structure, not the total

- length. (ie: the `max_len` of a Vec\<u32\> will be `max_len` \* 4)
|
|
|
|
|
|
|
+- The `max_len` attribute specifies the maximum number of elements in a Vec, not the total size in bytes.
|
|
|
|
|
+ For example, if you specify `#[max_len(10)]` for a `Vec<u32>`, it means:
|
|
|
|
|
+ - Maximum 10 elements
|
|
|
|
|
+ - Each element (u32) takes 4 bytes
|
|
|
|
|
+ - The Vec itself has a 4-byte length prefix
|
|
|
|
|
+ - Total space = 4 + (10 * 4) = 44 bytes
