Enum ssb_json_msg_data::json::EncodeJsonError

pub enum EncodeJsonError {
    Io(Error),
    InvalidFloat(f64),
    InvalidUnsignedInteger(u64),
    InvalidSignedInteger(i64),
    UnknownLength,
    Message(String),
}

Everything that can go wrong during json serialization.

Variants

Io(Error)

An IO error occured on the underlying writer.

When serializing directly into a Vec<u8> or String, this error never occurs.

InvalidFloat(f64)

Tried to serialize a number forbidden by the ssb data format (an inifinity, NaN or -0.0).

InvalidUnsignedInteger(u64)

Tried to serialize an unsigned integer larger than 2^53 (these are not guaranteed to be represented correctly in a 64 bit float).

InvalidSignedInteger(i64)

Tried to serialize an signed integer with absolute value larger than 2^53 (these are not guaranteed to be represented correctly in a 64 bit float).

UnknownLength

Can only serialize collections whose length is known upfront.

Message(String)

Custom, stringly-typed error.

Trait Implementations

impl Debug for EncodeJsonError

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

Formats the value using the given formatter.

impl Display for EncodeJsonError

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

Formats the value using the given formatter.

impl Error for EncodeJsonError

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 Error for EncodeJsonError

fn custom<T: Display>(msg: T) -> Self

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

impl From<Error> for EncodeJsonError

fn from(e: Error) -> Self

Performs the conversion.
