Enum CopyFormat 

pub enum CopyFormat {
    Text,
    Binary,
}

Wire format used by the Postgres COPY bulk path.

Defaults to Text for parity with PR #40 / the Phase-1 dispatcher. Binary is opt-in: it skips PG’s text parser, which is faster on BIGINT / TIMESTAMPTZ / UUID / NUMERIC-heavy schemas, but is at-best break-even on TEXT / JSONB / BYTEA- heavy ones because typed length prefixes inflate small payloads.

PG-only. Other backends ignore the field — their bulk paths are already protocol-native (TDS, MySQL LOAD DATA, ODPI-C).

Variants

Text

COPY … WITH (FORMAT TEXT). Tab-separated, newline-terminated; the only path before this flag existed.

Binary

COPY … WITH (FORMAT BINARY). Streamed via tokio_postgres::binary_copy::BinaryCopyInWriter; per-row values are bound through their ToSql impls.

Implementations

impl CopyFormat

pub fn parse(s: &str) -> Option<Self>

Parse a format name (case-insensitive). Recognised: text, binary.

Trait Implementations

impl Clone for CopyFormat

fn clone(&self) -> CopyFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CopyFormat

impl Debug for CopyFormat

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

Formats the value using the given formatter.

impl Default for CopyFormat

fn default() -> CopyFormat

Returns the “default value” for a type.

impl Eq for CopyFormat

impl PartialEq for CopyFormat

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