Struct NoteAttachmentScheme 

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

The user-defined type of a NoteAttachment.

A note attachment scheme is an arbitrary 32-bit unsigned integer.

Value 0 is reserved to signal that the scheme is none or absent. Whenever the kind of attachment is not standardized or interoperability is unimportant, this none value can be used.

Implementations

impl NoteAttachmentScheme

pub const fn new(attachment_scheme: u32) -> Self

Creates a new NoteAttachmentScheme from a u32.

pub const fn none() -> Self

Returns the NoteAttachmentScheme that signals the absence of an attachment scheme.

pub const fn is_none(&self) -> bool

Returns true if the attachment scheme is the reserved value that signals an absent scheme, false otherwise.

pub const fn as_u32(&self) -> u32

Returns the note attachment scheme as a u32.

Trait Implementations

impl Clone for NoteAttachmentScheme

fn clone(&self) -> NoteAttachmentScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoteAttachmentScheme

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

Formats the value using the given formatter.

impl Default for NoteAttachmentScheme

fn default() -> Self

Returns NoteAttachmentScheme::none.

impl Deserializable for NoteAttachmentScheme

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

impl Display for NoteAttachmentScheme

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

Formats the value using the given formatter.

impl PartialEq for NoteAttachmentScheme

fn eq(&self, other: &NoteAttachmentScheme) -> 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.

impl Serializable for NoteAttachmentScheme

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
