Implementations

impl LnurlPayRequestMetadata

pub fn from_email(email: &str) -> LnurlPayRequestMetadata

pub fn from_raw_string(raw: String) -> Result<LnurlPayRequestMetadata, Error>

Parses LNURL-pay metadata string into structured metadata.

LUD-06 metadata field is a JSON array encoded as a string: "[[\"text/plain\", \"lorem ipsum blah blah\"]]".

pub fn to_raw_string(&self) -> String

Serializes the metadata back into the raw LNURL-pay metadata string.

Generates a JSON array encoded as a string, suitable for use in LNURL-pay requests. The order of entries is deterministic.

Trait Implementations

impl Clone for LnurlPayRequestMetadata

fn clone(&self) -> LnurlPayRequestMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LnurlPayRequestMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for LnurlPayRequestMetadata

fn eq(&self, other: &LnurlPayRequestMetadata) -> bool
