Variants

UnrepresentableOffset

A host byte index cannot be represented by the compiler coordinate type.

Fields

offset: usize

max: usize

OffsetOutOfBounds

A byte offset is beyond the exclusive end of a source document.

Fields

offset: ByteOffset

len: ByteOffset

ReversedRange

The start of a range follows its end.

Fields

start: ByteOffset

end: ByteOffset

SourceMismatch

A range identifies a different source document.

Fields

expected: SourceId

actual: SourceId

SourceTooLarge

Source byte offsets must fit in the compiler’s u32 coordinate space.

Fields

len: usize

max: usize

TooManySources

All representable compilation-local IDs have been allocated.

impl Eq for SourceRangeError

impl Error for SourceRangeError

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<SourceRangeError> for DiagnosticReportError

fn from(source: SourceRangeError) -> Self

Converts to this type from the input type.
