Implementations

impl UserDefinedFunctionMetadata

pub fn link(&self) -> &str

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

pub fn identifier(&self) -> &str

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

pub fn body(&self) -> &str

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

pub fn compressed_binary(&self) -> &[u8]

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

pub fn runtime(&self) -> &str

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

pub fn version(&self) -> UdfExprVersion

Performs copy-assignment from source.

impl Debug for UserDefinedFunctionMetadata

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

Formats the value using the given formatter.

impl Default for UserDefinedFunctionMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UserDefinedFunctionMetadata

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for UserDefinedFunctionMetadata

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,

impl PartialEq for UserDefinedFunctionMetadata

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