Variants

Io(Error)

Corrupt

For malformed or truncated JSON the message is serde’s, position included, and detail has it structured (also for valid JSON a payload could not be read from).

Fields

message: String

detail: Option<JsonError>

NotThisFormat

Fields

expected: String

why: String

detail: Option<JsonError>

The serde error behind the refusal, when there was one (why is then its message).

WrongFormat

Fields

found: String

expected: String

TooNew

Fields

found: u64

supported: u64

TooOld

Fields

found: u64

oldest: u64

Migration

Fields

from: u64

msg: String

Encode(String)

Implementations

impl FormatError

pub fn corrupt(message: impl Into<String>) -> FormatError

A damaged file, for a reason that is not a serde error.

pub fn corrupt_json(context: &str, e: &Error) -> FormatError

A damaged file: serde’s error, its message after context when there is one.

pub fn json(&self) -> Option<&JsonError>

The serde error behind a FormatError::NotThisFormat or a FormatError::Corrupt, with its position.

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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<Error> for FormatError

fn from(source: Error) -> Self

Converts to this type from the input type.
