Function decode_raw_len 

pub const fn decode_raw_len(src_len: usize) -> usize

Returns the decoded output length for unpadded input.

Given the number of base64_url characters (no padding), calculates how many bytes will result from decoding.

Arguments

• src_len - Number of unpadded encoded characters

Returns

Number of decoded bytes

Example

use omp_core::base64_url;
// Encoding 5 bytes without padding produces chars; decoding yields 5 bytes
let data = [0u8; 5];
let encoded = base64_url::encode_raw(&data).into_vec();
assert_eq!(base64_url::decode_raw_len(encoded.len()), 5);
