TextCopyEncoder

Struct TextCopyEncoder 

Source
pub struct TextCopyEncoder { /* private fields */ }
Expand description

Encoder for text COPY IN format.

Text COPY format: tab-separated fields, newline-separated rows. Special values: \N for NULL, backslash escaping for special chars.

§Example

use sentinel_driver::copy::text::TextCopyEncoder;

let mut encoder = TextCopyEncoder::new();
encoder.add_row(&[Some("42"), Some("hello world")]);
encoder.add_row(&[Some("7"), None]); // NULL value

let data = encoder.finish();

Implementations§

Source§

impl TextCopyEncoder

Source

pub fn new() -> Self

Source

pub fn add_row(&mut self, fields: &[Option<&str>])

Add a row with the given field values.

None represents NULL (encoded as \N). Values are tab-separated, rows are newline-separated.

Source

pub fn finish(self) -> Vec<u8>

Finish encoding and return the text COPY data.

Source

pub fn len(&self) -> usize

Get the current buffer size.

Source

pub fn is_empty(&self) -> bool
