Enum ExpectedError 

pub enum ExpectedError {
    Separator {
        at: Option<usize>,
        got: Option<char>,
    },
    EndOfInput {
        at: Option<usize>,
        got: char,
    },
    Numeric {
        at: Option<usize>,
        got: Option<char>,
    },
}

An error type for faults relating to parsing and expecting a certain type of token.

Variants

Separator

When this error variant is returned, the . token, i.e. the separator, was expected, but a different token was present. The got field shows the token read.

Fields

at: Option<usize>

Place where the token was expected.

May be None if the respective parser does not store the index.

got: Option<char>

Token found instead, or None if we unexpectedly got the end-of-input.

EndOfInput

When this error variant is returned, the parser expected that no more tokens should be present, but instead 1 or more additional tokens were not parsed yet.

The got field contains the next token received, where it expected none to be remaining.

Fields

at: Option<usize>

Place where the end-of-input was expected.

May be None if the respective parser does not store the index.

got: char

Character found at the expected end-of-input.

Numeric

When this error variant is returned, a numeric token was expected, but a different token was present.

The got field shows the token read.

Fields

at: Option<usize>

Place where the token was expected.

May be None if the respective parser does not store the index.

got: Option<char>

Token found instead, or None if we unexpectedly got the end-of-input.

Trait Implementations

impl Clone for ExpectedError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpectedError

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

Formats the value using the given formatter.

impl Display for ExpectedError

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

Formats the value using the given formatter.

impl Eq for ExpectedError

impl Error for ExpectedError

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 From<ExpectedError> for ParserError

fn from(source: ExpectedError) -> Self

Converts to this type from the input type.

impl PartialEq for ExpectedError

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

Equality operator ==.

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

Inequality operator !=.
