Struct NoteAttachmentHeader 

pub struct NoteAttachmentHeader { /* private fields */ }

The header metadata for a single note attachment.

Contains the scheme of an attachment, without the actual content data.

Implementations

impl NoteAttachmentHeader

pub fn new(scheme: NoteAttachmentScheme) -> NoteAttachmentHeader

Creates a new NoteAttachmentHeader from a NoteAttachmentScheme.

pub fn new_maybe(scheme: Option<NoteAttachmentScheme>) -> NoteAttachmentHeader

Creates a new NoteAttachmentHeader from a NoteAttachmentScheme.

pub const fn absent() -> NoteAttachmentHeader

Returns a header representing the absence of an attachment.

pub const fn scheme(&self) -> Option<NoteAttachmentScheme>

Returns the attachment scheme.

pub const fn is_absent(&self) -> bool

Returns true if this header represents an absent attachment, false otherwise.

Trait Implementations

impl Clone for NoteAttachmentHeader

fn clone(&self) -> NoteAttachmentHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoteAttachmentHeader

impl Debug for NoteAttachmentHeader

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

Formats the value using the given formatter.

impl Default for NoteAttachmentHeader

fn default() -> NoteAttachmentHeader

Returns the “default value” for a type.

impl Deserializable for NoteAttachmentHeader

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

where R: ByteReader,

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

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

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

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

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

Deserializes Self from bytes with a byte budget limit.

impl Eq for NoteAttachmentHeader

impl From<NoteAttachmentScheme> for NoteAttachmentHeader

fn from(scheme: NoteAttachmentScheme) -> NoteAttachmentHeader

Converts to this type from the input type.

impl PartialEq for NoteAttachmentHeader

fn eq(&self, other: &NoteAttachmentHeader) -> 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 NoteAttachmentHeader

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

where W: ByteWriter,

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

fn get_size_hint(&self) -> usize

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

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

Serializes self into a vector of bytes.
