Struct SchemaResult

pub struct SchemaResult {
    pub schema: Bytes,
}

Wrap the result of a getSchema call

Fields

schema: Bytes

The schema of the dataset in its IPC form: 4 bytes - an optional IPC_CONTINUATION_TOKEN prefix 4 bytes - the byte length of the payload a flatbuffer Message whose header is the Schema

Trait Implementations

impl Clone for SchemaResult

fn clone(&self) -> SchemaResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaResult

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

Formats the value using the given formatter.

impl Default for SchemaResult

fn default() -> Self

Returns the “default value” for a type.

impl Message for SchemaResult

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 SchemaResult

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

fn try_from(data: &SchemaResult) -> Result<Self, ArrowError>

Performs the conversion.

impl TryFrom<SchemaAsIpc<'_>> for SchemaResult

type Error = ArrowError

The type returned in the event of a conversion error.

fn try_from(schema_ipc: SchemaAsIpc<'_>) -> Result<Self, ArrowError>

Performs the conversion.

impl TryFrom<SchemaResult> for Schema

type Error = ArrowError

The type returned in the event of a conversion error.

fn try_from(data: SchemaResult) -> Result<Self, ArrowError>

Performs the conversion.
