Enum PageError 

#[non_exhaustive]
pub enum PageError {
    TooBig {
        path: String,
        limit: u64,
    },
    TooMuch {
        limit: u64,
    },
    Layer(LayerError),
}

Why the page’s files could not be read into a layer (page_layer).

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.

TooBig

A file over the limit.

Fields

path: String

The file, as the page names it (files/stage.map).

limit: u64

The limit, in bytes.

TooMuch

The files together over the limit.

Fields

limit: u64

The limit, in bytes.

Layer(LayerError)

A path the layer refused (files/../x, files/a\b).

Trait Implementations

impl Debug for PageError

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

Formats the value using the given formatter.

impl Display for PageError

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

Formats the value using the given formatter.

impl Error for PageError

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.
