Enum ParseError 

#[non_exhaustive]
pub enum ParseError {
    OutOfBounds {
        value: String,
        bound: String,
    },
    UnknownFormat(String),
    UnknownFileType(String),
    WrongFormat {
        expected: &'static str,
        got: String,
    },
    AssertFail(String),
    UnsupportedVersion {
        format: &'static str,
        version: u32,
        supported: &'static [u32],
    },
    WrongBodyLength {
        format: String,
        got: u64,
        expected: u64,
    },
}

A file that violates its format: unknown tags or lengths, checksum mismatches, out-of-range values, unsupported schema versions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutOfBounds

Fields

value: String

bound: String

UnknownFormat(String)

UnknownFileType(String)

WrongFormat

A CBIN tag other than the one the reader was asked for. Formats sharing a body layout decode each other’s files without complaint, so the tag is the only thing that tells them apart.

Fields

expected: &'static str

got: String

AssertFail(String)

UnsupportedVersion

A file whose schema version this build has never been validated against.

Field offsets are only known to be right for the versions in the corpus. Decoding a newer one would produce plausible-looking but wrong values, and writing it back would then persist them — so refuse instead.

Fields

format: &'static str

version: u32

supported: &'static [u32]

WrongBodyLength

A body whose length is not the one the format declares — a truncated or padded file on read, a miscounting writer on write.

Fields

format: String

got: u64

expected: u64

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<!> for ParseError

Lets an infallible decode sit alongside fallible ones behind the same ?.

fn from(never: Infallible) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.
