Errors that can occur during file I/O operations

Variants

FileOpenError

File could not be opened for reading

Fields

path: PathBuf

Path to the file that could not be opened

source: Error

Underlying I/O error

MmapError

File could not be memory-mapped

Fields

path: PathBuf

Path to the file that could not be mapped

source: Error

Underlying I/O error

EmptyFile

File is empty and cannot be processed

Fields

path: PathBuf

Path to the empty file

FileTooLarge

File is too large to be processed safely

Fields

path: PathBuf

Path to the file that is too large

size: u64

Actual file size in bytes

max_size: u64

Maximum allowed file size in bytes

MetadataError

File metadata could not be read

Fields

path: PathBuf

Path to the file whose metadata could not be read

source: Error

Underlying I/O error

BufferOverrun

Buffer access out of bounds

Fields

offset: usize

Requested offset

length: usize

Requested length

buffer_size: usize

Actual buffer size

InvalidAccess

Invalid offset or length parameter

Fields

offset: usize

Requested offset

length: usize

Requested length

InvalidFileType

File is not a regular file (e.g., device node, FIFO, symlink to special file)

Fields

path: PathBuf

Path to the file that is not a regular file

file_type: String

Description of the file type

Trait Implementations

impl Debug for IoError

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

Formats the value using the given formatter.

impl Display for IoError

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

Formats the value using the given formatter.

impl Error for IoError

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<IoError> for LibmagicError

fn from(err: IoError) -> Self

Converts to this type from the input type.
