Enum FormatPreference 

#[non_exhaustive]
pub enum FormatPreference {
    Arrow,
    Tlv,
    Csv,
}

Format the publisher will emit batches in once a subscription is accepted.

Mirrors lightstream’s format options.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Arrow

Arrow IPC stream protocol, the default high-throughput choice.

Tlv

Lightstream TLV framing for opaque payloads.

Csv

Streaming CSV, intended for ad-hoc inspection rather than throughput.

Trait Implementations

impl Clone for FormatPreference

fn clone(&self) -> FormatPreference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatPreference

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

Formats the value using the given formatter.

impl Default for FormatPreference

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FormatPreference

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FormatPreference

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

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 PartialEq for FormatPreference

fn eq(&self, other: &FormatPreference) -> 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 serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
