Enum FatError 

#[non_exhaustive]
pub enum FatError {
    Io {
        op: &'static str,
        source: Error,
    },
    InvalidBoot(String),
    NotFat(String),
    Corrupt(String),
}

Errors raised while opening or navigating a FAT/exFAT volume.

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.

Io

Underlying reader failed during the named operation.

Fields

op: &'static str

The operation being attempted (e.g. "read boot sector").

source: Error

The originating I/O error.

InvalidBoot(String)

The boot sector is structurally invalid; the message names the offending field and value (fail-loud, show-the-value).

NotFat(String)

The volume is not a recognized FAT or exFAT filesystem; the message carries the bytes/signature that were found instead.

Corrupt(String)

A structure was internally inconsistent while navigating.

Implementations

impl FatError

pub fn io(op: &'static str, source: Error) -> Self

Wrap an I/O error with the operation label. Public so downstream analyzers can surface their own reads as typed FatErrors.

Trait Implementations

impl Debug for FatError

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

Formats the value using the given formatter.

impl Display for FatError

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

Formats the value using the given formatter.

impl Error for FatError

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.
