Struct WScriptHash 

pub struct WScriptHash(/* private fields */);

SegWit (256-bit) version of a Tidecoin script bytecode hash.

Implementations

impl WScriptHash

pub fn from_script( witness_script: &WitnessScript, ) -> Result<Self, WitnessScriptSizeError>

Constructs a new WScriptHash after first checking the script size.

10,000-byte limit on the witness script

The witnessScript (≤ 10,000 bytes) is popped off the initial witness stack. SHA256 of the witnessScript must match the 32-byte witness program.

Errors

Returns an error if the script exceeds 10,000 bytes.

pub fn from_script_unchecked(script: &WitnessScript) -> Self

Constructs a new WScriptHash from any script irrespective of script size.

If you hash a script that exceeds 10,000 bytes in size and use it to create a Segwit output then the output will be unspendable.

impl WScriptHash

pub const fn from_byte_array(bytes: [u8; 32]) -> Self

Constructs a new type from the underlying byte array.

pub const fn to_byte_array(self) -> [u8; 32]

Returns the underlying byte array.

pub const fn as_byte_array(&self) -> &[u8; 32]

Returns a reference to the underlying byte array.
