Struct JsonOptions 

pub struct JsonOptions {
    pub compression: i32,
    pub schema_infer_max_rec: Option<u64>,
    pub compression_level: Option<u32>,
    pub newline_delimited: Option<bool>,
}

Options controlling CSV format

Fields

compression: i32

Compression type

schema_infer_max_rec: Option<u64>

Optional max records for schema inference

compression_level: Option<u32>

Optional compression level

newline_delimited: Option<bool>

Whether to read as newline-delimited JSON (default true). When false, expects JSON array format [{},…]

Implementations

impl JsonOptions

pub fn compression(&self) -> CompressionTypeVariant

Returns the enum value of compression, or the default if the field is set to an invalid enum value.

pub fn set_compression(&mut self, value: CompressionTypeVariant)

Sets compression to the provided enum value.

pub fn schema_infer_max_rec(&self) -> u64

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

pub fn compression_level(&self) -> u32

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

pub fn newline_delimited(&self) -> bool

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

Trait Implementations

impl Clone for JsonOptions

fn clone(&self) -> JsonOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonOptions

impl Debug for JsonOptions

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

Formats the value using the given formatter.

impl Default for JsonOptions

fn default() -> JsonOptions

Returns the “default value” for a type.

impl Eq for JsonOptions

impl From<&JsonFormatFactory> for JsonOptions

Available on crate feature proto only.

Encode a JsonFormatFactory’s options as their protobuf form.

The reverse direction is From<&protobuf::JsonOptions> for JsonOptions in datafusion-proto-models: JsonOptions is a datafusion-common type, so that half cannot live here.

fn from(factory: &JsonFormatFactory) -> JsonOptions

Converts to this type from the input type.

impl Hash for JsonOptions

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 JsonOptions

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 JsonOptions

fn eq(&self, other: &JsonOptions) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
