Implementations

impl MetaData

pub fn is_multi_part(&self) -> bool

Returns the value of is_multi_part, or the default value if is_multi_part is unset.

pub fn content_type(&self) -> &str

Returns the value of content_type, or the default value if content_type is unset.

pub fn size(&self) -> u64

Returns the value of size, or the default value if size is unset.

pub fn seq(&self) -> u64

Returns the value of seq, or the default value if seq is unset.

pub fn file_name(&self) -> &str

Returns the value of file_name, or the default value if file_name is unset.

pub fn file_type(&self) -> &str

Returns the value of file_type, or the default value if file_type is unset.

pub fn md5(&self) -> &str

Returns the value of md5, or the default value if md5 is unset.

pub fn description(&self) -> &str

Returns the value of description, or the default value if description is unset.

Trait Implementations

impl Clone for MetaData

fn clone(&self) -> MetaData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetaData

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

Formats the value using the given formatter.

impl Default for MetaData

fn default() -> Self

Returns the “default value” for a type.

impl From<MetaData> for MetaData

fn from(value: MetaData) -> Self

Converts to this type from the input type.

impl Message for MetaData

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for MetaData

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