Enum DiskError 

pub enum DiskError {
    InsufficientSpace {
        required: u64,
        available: Option<u64>,
    },
    IoError(String),
    PermissionDenied(String),
}

Structured error type for disk-related failures during download.

Provides specific error variants for different disk failure scenarios, enabling callers to handle each case appropriately (e.g., show user-friendly messages, trigger cleanup, or retry with smaller files).

Examples

use aria2_core::filesystem::disk_space::DiskError;

match check_disk_space(path, required_bytes) {
    Ok(()) => println!("Sufficient space"),
    Err(DiskError::InsufficientSpace { required, available }) => {
        eprintln!("Need {} but only {} available", required, available.unwrap_or(0));
    }
    Err(DiskError::IoError(msg)) => eprintln!("I/O error: {}", msg),
    Err(DiskError::PermissionDenied(p)) => eprintln!("Permission denied: {}", p),
}

Variants

InsufficientSpace

Not enough disk space available

Fields

required: u64

Bytes required for the operation

available: Option<u64>

Bytes currently available (None if unknown)

IoError(String)

General I/O error during disk operation

PermissionDenied(String)

Permission denied when accessing path

Trait Implementations

impl Clone for DiskError

fn clone(&self) -> DiskError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiskError

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

Formats the value using the given formatter.

impl Display for DiskError

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

Formats the value using the given formatter.

impl Error for DiskError

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.
