Enum Error 

pub enum Error {
    Block(Error),
    Io(Error),
    NoPartitionTable,
    GptHeaderCrc,
    GptEntriesCrc,
    GptCorrupt(&'static str),
    MbrCorrupt(&'static str),
    GptBackupMismatch(&'static str),
    Invalid(&'static str),
    DeviceTooSmall,
}

Variants

Block(Error)

Block-layer error (read failure, short read, etc.). Lifted from fs_core::Error so any BlockRead failure flows up unchanged.

Io(Error)

Underlying I/O failure that didn’t go through fs-core (rare — retained for direct std::io::Error sources).

NoPartitionTable

No GPT signature and no MBR signature found.

GptHeaderCrc

GPT header was located but failed CRC validation.

GptEntriesCrc

GPT partition-entry array failed CRC validation.

GptCorrupt(&'static str)

GPT header field combination is internally inconsistent.

MbrCorrupt(&'static str)

MBR signature missing or extended-partition chain broken.

GptBackupMismatch(&'static str)

GPT primary header and backup header disagree on the partition list, header fields, or entry-array CRC. Carries a short reason string. The probe path treats this as advisory by default — the variant only surfaces if a caller explicitly asks for backup validation.

Invalid(&'static str)

Mutation API rejected an input: overlap, out-of-bounds, alignment impossible, etc. Carries a short reason string.

DeviceTooSmall

Mutation API tried to write a partition table that does not fit the device, or the device is too small for the chosen table type.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
