Enum SourcePositionError 

pub enum SourcePositionError {
    ByteOffsetOutOfBounds {
        offset: usize,
        len: usize,
    },
    ByteOffsetInsideCodePoint {
        offset: usize,
    },
    Utf16PositionOutOfBounds {
        position: Utf16Pos,
        len: Utf16Pos,
    },
    Utf16PositionInsideSurrogatePair {
        position: Utf16Pos,
    },
    RangeStartAfterEnd {
        start: Utf16Pos,
        end: Utf16Pos,
    },
}

A failed checked source-position operation.

This enum is deliberately closed: callers can exhaustively distinguish an out-of-bounds coordinate from a coordinate that splits one encoded character.

impl Eq for SourcePositionError

impl Error for SourcePositionError

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
