Enum LoadError 

#[non_exhaustive]
pub enum LoadError {
    LibraryNotFound {
        searched: Vec<String>,
    },
    OpenFailed {
        path: PathBuf,
        source: Error,
    },
    MissingSymbol(MissingSymbolError),
}

Failure to locate, open, or validate the PDFium shared library.

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.

LibraryNotFound

No candidate library was found. Contains every location that was tried, in discovery order.

Fields

searched: Vec<String>

Every location tried, in discovery order.

OpenFailed

A concrete library file was found (or explicitly given) but the dynamic loader failed to open it.

Fields

path: PathBuf

The library file that failed to open.

source: Error

The dynamic loader’s error.

MissingSymbol(MissingSymbolError)

The library opened, but a required PDFium symbol is missing — the build is older than the oldest version this crate supports, or the file is not PDFium at all.

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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<LoadError> for Error

fn from(e: LoadError) -> Self

Converts to this type from the input type.
