Crate tape_base58 

Base58 encoding and decoding for Solana-shaped data

Public keys and signatures get fixed-size paths that avoid the long division a general base58 codec performs. Everything else goes through a limb-based codec that is still far cheaper than the byte-at-a-time form. The widest instruction set the running machine supports is chosen at first use, so a build carrying no target flags still gets the fast path.

Functions

decode

Decode characters of any length up to the codec’s limit

decode_32

Decode a public key, rejecting anything that is not exactly 32 bytes wide

decode_64

Decode a signature, rejecting anything that is not exactly 64 bytes wide

decode_32_batch

Decode many public keys, one output each

decode_64_batch

Decode many signatures, one output each

decoded_len

Most bytes an encoding of this many characters can produce

encode

Encode bytes of any length up to the codec’s limit

encode_32

Encode a public key, returning how many bytes of the output were written

encode_64

Encode a signature, returning how many bytes of the output were written

encode_32_batch

Encode many public keys, one output slot of the maximum width each

encode_64_batch

Encode many signatures, one output slot of the maximum width each

encoded_len

Longest encoding an input of this many bytes can produce
