Enum IndexError 

pub enum IndexError {
    Read {
        path: PathBuf,
        source: Error,
    },
    Parse {
        path: PathBuf,
        source: Error,
    },
    Serialize {
        path: PathBuf,
        source: Error,
    },
    Path {
        source: PathError,
    },
    NoConfigDir,
}

Failure modes when loading or operating on a GlobalIndex.

Variants

Read

I/O error reading the index file.

Fields

path: PathBuf

File the loader tried to read.

source: Error

Underlying I/O error.

Parse

TOML deserialization error.

Fields

path: PathBuf

File the parser tried to read.

source: Error

Underlying TOML deserialization error.

Serialize

TOML serialization error — surfaced by GlobalIndex::save_to.

Fields

path: PathBuf

File the writer was about to write to.

source: Error

Underlying TOML serialization error.

Path

One of the keys in the index did not satisfy the path convention from ADR-020 §2.

Fields

source: PathError

Underlying path-validation error.

NoConfigDir

dirs::config_dir() returned None — extremely unusual on supported platforms but worth surfacing rather than panicking.

Trait Implementations

impl Debug for IndexError

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

Formats the value using the given formatter.

impl Display for IndexError

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

Formats the value using the given formatter.

impl Error for IndexError

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<IndexError> for Error

fn from(e: IndexError) -> Self

Converts to this type from the input type.
