Enum AccessError 

#[non_exhaustive]
pub enum AccessError {
    PermissionRevoked,
    Io {
        source: Error,
    },
    InvalidDescriptor,
    Platform {
        message: String,
    },
}

Errors that can occur when opening or accessing a previously granted file.

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.

PermissionRevoked

Io

An I/O error occurred while reading from or writing to the file.

Fields

source: Error

The underlying I/O error.

InvalidDescriptor

The file descriptor or handle returned by the platform was invalid.

Platform

The platform returned an error when attempting to open the file.

Fields

message: String

Human-readable description of the platform error.

Trait Implementations

impl Debug for AccessError

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

Formats the value using the given formatter.

impl Display for AccessError

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

Formats the value using the given formatter.

impl Error for AccessError

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 AccessError

fn from(source: Error) -> Self

Converts to this type from the input type.
