Enum FragmentError 

pub enum FragmentError {
    Collision {
        key: String,
        first: String,
        second: String,
    },
}

Failures from building a FragmentTable.

Variants

Collision

Two different fragments claim the same key. The build stops here rather than picking one, because either choice silently changes what half the use sites render.

Fields

key: String

The contested key.

first: String

Where the fragment already in the table came from.

second: String

Where the rejected declaration came from.

Trait Implementations

impl Debug for FragmentError

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

Formats the value using the given formatter.

impl Display for FragmentError

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

Formats the value using the given formatter.

impl Error for FragmentError

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.
