Enum YsonError 

pub enum YsonError {
    Eof,
    UnexpectedEof(usize),
    InvalidMarker(u8, usize),
    MalformedVarint(usize),
    InvalidUtf8(usize),
    UnexpectedToken {
        expected: &'static str,
        found: String,
        pos: usize,
    },
    Custom(String),
}

Errors that can occur during YSON serialization or deserialization.

Variants

Eof

Reached the end of the input stream gracefully.

UnexpectedEof(usize)

Reached the end of the input unexpectedly (e.g., in the middle of a string). Contains the byte position where the EOF was encountered.

InvalidMarker(u8, usize)

Encountered a byte that is not a valid YSON marker. Contains the invalid byte and its position.

MalformedVarint(usize)

Failed to parse a variable-length integer (varint). Contains the starting position of the malformed varint.

InvalidUtf8(usize)

Encountered a string that is not valid UTF-8. Contains the starting position of the invalid string.

UnexpectedToken

Found a token that does not match the expected YSON structure.

Fields

expected: &'static str

A description of what the parser was looking for.

found: String

A string representation of the token that was actually found.

pos: usize

The byte position of the unexpected token.

Custom(String)

A catch-all for custom errors produced by serde or the user’s data types.

Trait Implementations

impl Clone for YsonError

fn clone(&self) -> YsonError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for YsonError

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

Formats the value using the given formatter.

impl Display for YsonError

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

Formats the value using the given formatter.

impl Error for YsonError

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 Error for YsonError

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl Error for YsonError

fn custom<T: Display>(msg: T) -> Self

Used when a Serialize implementation encounters any error while serializing a type.

impl PartialEq for YsonError

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

Equality operator ==.

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

Inequality operator !=.
