Struct ParseError 

pub struct ParseError {
    pub message: String,
    pub token_pos: usize,
}

Fields

message: String

token_pos: usize

Index into the token stream where parsing tripped. Not a byte offset. v7.39 (read01 round 95) — the byte/char position is NOT stored here: a field would grow every Result<_, ParseError> slot on the deeply recursive parse stack and tip the nesting-budget frame cliff. PG’s 1-based char position is recovered on the cold error path by syntax_error_position, which re-tokenizes to map this token index.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

v7.39 (round 322/V24) — the message ALONE. It used to be prefixed with parse error at token #N: , which PG has no equivalent of: the message bodies are already PG’s verbatim (LIMIT must not be negative, invalid input syntax for type bigint: "abc"), and the prefix was SPG’s internal token index leaking into every one of them. token_pos stays a field — the wire recovers PG’s 1-based character position from it for the ErrorResponse P.
