Enum LayerError

pub enum LayerError<E> {
    Missing {
        uri: String,
        importer: Option<String>,
    },
    Resolver {
        uri: String,
        importer: Option<String>,
        source: E,
    },
    Read {
        key: String,
        source: ReadError,
    },
    Integrity {
        uri: String,
        importer: String,
        source: IntegrityError,
    },
    Cycle {
        chain: Vec<String>,
    },
}

Why a layer stack could not be built. E is the resolver’s error type.

Variants

Missing

The resolver has no layer for this import.

Fields

uri: String

importer: Option<String>

Key of the importing layer; None for the main layer.

Resolver

The resolver failed.

Fields

uri: String

importer: Option<String>

source: E

Read

A loaded layer is not a valid IFCX file.

Fields

key: String

source: ReadError

Integrity

The bytes of an imported layer do not satisfy the import’s integrity, or the value cannot be checked.

Fields

uri: String

importer: String

source: IntegrityError

Cycle

Layers import each other in a loop. chain lists the keys along the loop and ends with the key it starts with.

Fields

chain: Vec<String>

Trait Implementations

impl<E: Debug> Debug for LayerError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for LayerError<E>

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

Formats the value using the given formatter.

impl<E> Error for LayerError<E>

where E: Error + 'static,

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>)
