Implementations

impl RsonError

pub fn syntax_error<S>(message: S, line: usize, column: usize) -> RsonError

where S: Into<String>,

Create a new syntax error.

pub fn invalid_character<S>( found: char, expected: S, position: usize, ) -> RsonError

where S: Into<String>,

Create a new invalid character error.

pub fn type_mismatch<S>(expected: S, found: S) -> RsonError

where S: Into<String>,

Create a new type mismatch error.

pub fn custom<S>(message: S) -> RsonError

where S: Into<String>,

Create a new custom error.

Trait Implementations

impl Clone for RsonError

fn clone(&self) -> RsonError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RsonError

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

Formats the value using the given formatter.

impl Display for RsonError

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

Formats the value using the given formatter.

impl Error for RsonError

Available on crate feature std only.

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<Err<Error<&str>>> for RsonError

fn from(err: Err<Error<&str>>) -> RsonError

Converts to this type from the input type.

impl From<Err<VerboseError<&str>>> for RsonError

fn from(err: Err<VerboseError<&str>>) -> RsonError

Converts to this type from the input type.

impl PartialEq for RsonError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
