pub fn none() -> Memo

Create new empty memo.

pub fn id(id: u64) -> Memo

Create new id memo.

pub fn text<S: Into<String>>(text: S) -> Result<Memo>

Create new text memo. text must be shorter than 28 bytes.

pub fn hash(h: [u8; 32]) -> Memo

Create new hash memo.

pub fn return_(r: [u8; 32]) -> Memo

Create new return memo.

pub fn is_none(&self) -> bool

Return true if memo is None.

pub fn is_id(&self) -> bool

Return true if memo is Id.

pub fn is_text(&self) -> bool

Return true if memo is Text.

pub fn is_hash(&self) -> bool

Return true if memo is Hash.

pub fn is_return(&self) -> bool

Return true if memo is Return.

Trait Implementations

impl Clone for Memo

fn clone(&self) -> Memo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Memo

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

Formats the value using the given formatter.

impl PartialEq for Memo

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
