Enum Encoding 

#[repr(C)]
pub enum Encoding {
    Base64UrlNoPad = 0,
}

Encoding available to ConstraintExpr::Decode.

Wire-format note: variants must only be appended, never reordered.

Variants

Base64UrlNoPad = 0

base64url without padding: RFC 4648 section 5, the alphabet and the omitted padding that JWS and COSE use.

Implementations

impl Encoding

pub const fn decoded_bits(&self, encoded_bits: u32) -> Option<u32>

Width of the decoded form in bits, given the width of the encoded form.

None when nothing of that width decodes at all, so an operand that could never be evaluated is rejected when the gate is validated rather than by every peer at runtime. For unpadded base64 that is any character count congruent to 1 mod 4: a lone trailing character carries 6 bits and the byte it would start needs 8.
