Struct ParseError 

pub struct ParseError {
    pub message: String,
    pub position: usize,
    /* private fields */
}

A parse/lex error. message is the full, ready-to-display text (the #[error] format is just "{message}"), so the 42601 “syntax error at position N: …” framing is baked in by new, while a 54001 depth error (built by too_deep) renders its own PostgreSQL-faithful text verbatim.

Fields

message: String

position: usize

Implementations

impl ParseError

pub fn new(message: impl Into<String>, position: usize) -> Self

pub fn too_deep(position: usize) -> Self

A recursion-depth-limit error: the statement nests more deeply than the parser’s MAX_DEPTH allows. Maps to SQLSTATE 54001 (statement_too_complex) with PostgreSQL’s “stack depth limit exceeded” message, so a maliciously deep query returns a clean error instead of overflowing the stack and aborting the server process.

impl Eq for ParseError

impl Error for ParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
