Structs

TermMap

DEPRECATED: ETF Term-based map wrapper (legacy) Use vecpak::PropListMap instead for the primary vecpak format. This struct is kept for backwards compatibility with legacy ETF code only.

Traits

TermExt

DEPRECATED: Lightweight helpers for ETF Term manipulation (legacy) Use vecpak::VecpakExt trait instead for the primary vecpak format. This trait is kept for backwards compatibility with legacy ETF code only.

Typename

Trait for types that can provide their type name as a static string

Functions

alphanumeric

ascii

Keep only ASCII characters considered printable for our use-case.

bcat

Concatenate multiple byte slices into a single Vec Example: bcat(&[b“bic:coin:balance:“, pk, b”:AMA“])

bin_to_bitvec

bitvec_to_bin

decode_base58_array

Decode base58 string to fixed-size byte array Returns None if decoding fails or size doesn’t match

decode_base58_hash

Decode base58 string to 32-byte hash

decode_base58_pk

Decode base58 string to 48-byte public key

eetf_list_of_binariesDeprecated

DEPRECATED: Encode a list of binary values as ETF term Use list_of_binaries_to_vecpak instead for new code.

format_duration

Creates string representation as bytes, compatible with Erlang’s :erlang.integer_to_binary/1 Format a duration into human-readable form following the requirements:

get_bits_percentage

Calculate percentage of true bits in a mask relative to total count

get_unix_millis_now

get_unix_nanos_now

get_unix_secs_now

hexdump

Produce a hex dump similar to hexdump -C for a binary slice.

is_alphanumeric

is_ascii_clean

list_of_binaries_to_vecpak

parse_list

Parse a list of ETF terms into structured data using the provided parser

pk_hexDeprecated

DEPRECATED: This function incorrectly uses base58 encoding Elixir uses raw binary pubkeys in keys, not base58 Use bcat() instead for building binary keys

serialize_list

Serialize a list of items into an ETF List term using the provided serializer

url

Trim trailing slash from url

url_with

Trim trailing slash on base and append path verbatim
