assert_ok

Panic if the expression is not Ok(_).

bhash

Validates a block hash at compile time. Requires BlockHash to be in scope.

Structs

Ema

Exponential moving average (EMA) over scalar samples.

Functions

get_hash_from_u8

Computes the SHA-256 digest of the byte slice data and returns a Hash from bitcoin_hashes.

get_spk_hash

Computes the SHA-256 digest of a script, reverses its bytes, and returns a Hash from bitcoin_hashes.

parse_descriptors

Takes an array of descriptors as String, performs sanity checks on each one and returns list of parsed descriptors.

read_bounded_len
