pub const BASE_MINT_LEN: usize = 82;Expand description
Length of a plain (non-extended) mint’s data region.
This is the stride of the Mint base struct; it is not the
offset at which mint extensions begin (see TLV_OFFSET). Used
for the length-only check that distinguishes a legacy SPL mint
(exactly 82 bytes) from an extended Token-2022 mint.
