Struct CopyOptions 

pub struct CopyOptions {
    pub format: CopyFormat,
    pub header: bool,
    pub delimiter: Option<char>,
    pub null_str: Option<String>,
    pub quote: Option<char>,
    pub escape: Option<char>,
    pub force_quote: Option<Vec<String>>,
    pub force_not_null: Option<Vec<String>>,
    pub force_null: Option<Vec<String>>,
}

Options for COPY … TO STDOUT [WITH] (…). Defaults reproduce the bare COPY … TO STDOUT text-format behaviour, so an empty option list is a no-op. delimiter / null_str / quote fall back to the per-format defaults (text: \t / \N; csv: , / `` / ") when unset.

Fields

format: CopyFormat

header: bool

delimiter: Option<char>

null_str: Option<String>

quote: Option<char>

escape: Option<char>

v7.39 (round 247) — CSV ESCAPE: the character that precedes a quote (or itself) inside a quoted cell. Defaults to the quote character (PG’s doubling behavior).

force_quote: Option<Vec<String>>

v7.39 (round 247) — CSV FORCE_QUOTE (col, …) / FORCE_QUOTE *: columns whose non-NULL cells always quote. Some(vec![]) is the * spelling (every column).

force_not_null: Option<Vec<String>>

v7.39 (round 265) — CSV FORCE_NOT_NULL (col, …): for these columns an UNQUOTED empty field reads as the empty string rather than NULL (probed). COPY FROM only.

force_null: Option<Vec<String>>

v7.39 (round 265) — CSV FORCE_NULL (col, …): for these columns a QUOTED empty field ("") also reads as NULL (probed). COPY FROM only.
