Enum access_json::QueryParseErr

pub enum QueryParseErr {
    BadCharacter(usize),
    MissingField,
    MissingNumber(usize),
    BadArray(usize),
    BadField(usize),
    UnexpectedEOF(char),
    Unexpected(usize, char),
    BadIndex(usize, String),
}

An enum representing errors possible while parsing a query.

All usize fields in these errors represent the character index where the parser detected the failure.

Variants

BadCharacter(usize)

Each parsable element must start with '.' or '['

MissingField

Need a field name; encountered a ".." in the query.

MissingNumber(usize)

Need a number; encountered a "[]" in the query.

BadArray(usize)

Got some kind of non-decimal digit inside the brackets "[]".

BadField(usize)

Got some kind of bad character (or whitespace) inside a '.'

UnexpectedEOF(char)

Reached the end of the string while looking for a specific character (probably ']')

Unexpected(usize, char)

Found a strange character at the given position.

BadIndex(usize, String)

Could not parse the number in your brackets to a usize. String is the IntError in question.

Trait Implementations

impl Clone for QueryParseErr

fn clone(&self) -> QueryParseErr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryParseErr

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

Formats the value using the given formatter.

impl Display for QueryParseErr

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

Formats the value using the given formatter.

impl Eq for QueryParseErr

impl Error for QueryParseErr

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<QueryParseErr> for QueryParseErr

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for QueryParseErr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
